Question: Are your HOCL-45 and HOCL-90/45H angle clips DSA compliant?
Please see the HOCL-45 & HOCL-9045H Submittal Sheet.
The submittal sheet includes both cut sheets showing overall dimensions and a representative image of the clips. As well as excerpts from California DSA IR 25-2.13 REV. 11-09-17, specifically pages 34 & 37.
Part #: HOCL-45
If you look at the second figure on “Sheet No. 4.10” titled “Bracing Wire”, it shows the 45-degree angle clip requirements for bracing wire.
½” TYP from edge to center of the hole where the ceiling wire is tied (HOCL-45 meets this spec).
½” MAX. U.O.N. from edge to center of the hole for the 3/8″ expansion anchor (HOCL-45 meets this spec).
Here are images of the measurements mentioned above as well as a mic. on the 12 gauge thickness:
Part #: HOCL-90/45H
If you look at the first figure on Sheet No. 4.21 titled “Option 1″, it shows a 12 GA X 1″ wide angle clip with a hole for a 3/8″ dia. expansion anchor (HOCL-90/45H meets this spec). It also shows ½” MAX. from edge to center of the hole for a 3/8″ expansion anchor (HOCL-90/45H meets this spec).
You may ask, is DSA compliance acceptable if there is no ICC-ES report?
The specifications called out in DSA IR-25-2.13 are met or exceeded by our clips as is evident in the measurement images posted above.
According to DSA IR A-5 “Acceptance of Product Materials, and Evaluation Reports”, Section 1.1 states “Products, including alternate materials, must have a valid evaluation listing/report issued by a recognized evaluation agency.”
Section 3. VALID LISTINGS…
Section 3.1 “The product or material must comply with CBC. Evaluation reports may not be acceptable if the product does not comply with applicable DSA amendments contained in CBC and/or applicable DSA IRs, or Bulletins.”
Section 3.3 Goes on to list the acceptable evaluation reports in order (ICC ES, IAPMO ES, OSHPD, COLA, NOA). If none of those are available for the product, the last bullet states:
* Other product certification bodies that are certified to be in compliance with ISO/IEC 17065:2012, “Requirements for Bodies Certifying Products, Processing and Services” (for projects submitted under the 2016 and 2013 CBC) and ISO Guide 65, “General Requirements for Bodies Operating Product Certification Systems” (for projects submitted under the 2010 and 2007 CBC).
In essence, in the absence of a third party evaluate report, as long as a product complies with the requirements of CBC, DSA IRS and bulletins, and can be traced with a marking, any certification body that is in compliance with the standards mentioned above may certify compliance.
Furthermore, To the best of our knowledge, no manufacturer has a current ICC-ES report on similar angle clips.
Hilti’s X-CC 45 does not have an ICC per their report here: https://www.hilti.com/medias/sys_master/documents/h35/hc8/9400251285534/Technical-information-ASSET-DOC-LOC-1577839.pdf
The report listed on their product page for the X-CC 45 is only for:
“Ceiling fastening system Applicable base material Fastener types Recommended installation tools Wire type Section X-CX C Concrete, lightweight concrete over metal deck X-C27 DX 351-CT with Pole Tool Pre-tied to ceiling clip or provided by others 3.3.2 X-CX ALH Concrete, lightweight concrete over metal deck, steel X-ALH 22, X-ALH 27, X-ALH 32 DX 351-CT with Pole Tool Pre-tied to ceiling clip or provided by others 3.3.2 Eye-lag screw Wood, sheet steel EL WS, EL S, EL SD Telescopic Screw Ceiling Tool Provided by others 3.3.3”
Tomarco, Powers/DeWALT do not have an ICC-ES report on similar angle clips either.
We’re excited to announce a new feature on our Doc’s Industries website. On every product page, just below the blue “Where to buy” button, there is now an orange “Submittal Request” button. This button allows you to quickly and easily request a submittal sheet on the product you are viewing. We hope that this new option will help you and your customers navigate the submittal process with minimal effort.
Your ICC-ES report lists two different holding values, ASD and LRFD. What do these two acronyms stand for?
Our ICC-ES report ESR 3135 refers to two methods of calculating the strength of a fastener in steel. ASD (Allowable Strength Design) and LRFD (Load & Resistance Factor Design). Both ASD and LRFD are structural design terms and are used by structural engineers to determine allowable loads under different structural design criteria.
Are the HOCL-1 and HOCL-45 angle clips ICC listed like other brands?
California Division of the State Architect (DSA) compliance has been found to be sufficient for stand-alone angle clips. Both the HOCL-1 and the HOCL-45 comply with California DSA. See page 22 of DSA IR 25-2.13 – Appendix A below.
Please note ½” max from center to edge, and ½” TYP (typical) from bottom edge to wire tying hole for #12 gauge wire.
We have not been able to find a stand-alone angle clip that is ICC listed. As far as we can tell, the ICC listings that have been published by other brands apply to their pin and clip assemblies, not to the angle clip by itself.
For example, Ramset part #: 1202CF is not shown anywhere on their ICC report located here: https://www.icc-es.org/wp-content/uploads/report-directory/ESR-1799.pdf
It only lists the “SP” & “SPC” part numbers for the assemblies as is shown in the image below.
The same applies for DeWALT/Powers and Hilti:

HILTI TECHNICAL DATA GUIDE:
14 gauge sheet metal is difficult to drill into with our self-drilling eye lag screws. There are several variables which can affect the ability of the screw to set correctly.
Principally, the variables are thickness of the metal, tensile strength of the metal and skill of the installer.
The 750 SD was designed to be installed in 18 gauge sheet metal (0.0478” thick). This is the thickness of most of the metal decking that the 750 SD is installed in.
During installation, the 750 SD threads into the sheet metal. The core of the threads is about 0.190” in diameter. This core is forced into a 0.165” hole made by the drill point.
In other words, the sheet metal is forced to expand beyond the size of the hole drilled by the drill point.
The 750 SD will work with 16 Gauge (0.0598” thick) if the screw is carefully installed. But please note, if too much force is used, the screw could snap or strip out in the deck.
I really do not see how the 750 SD could penetrate and thread into anything thicker than 16 gauge. However, the only way to be certain is to actually attempt an installation.
Perhaps the ELDX self-drilling screw would be a better choice, as it is designed for thicker material and has a larger diameter drill point. We know that the ELDX works well in 12 gauge (0.1046” thick) material. Here again, the skill of the installer is an important variable as the ELDX could “strip out” if the installer isn’t careful.
Many installers use the 750 SD in purlin or red iron.
However, they cannot fully set the screw all the way to the collar in red iron or purlin because the metal has a high tensile strength, even if the metal it is relatively thin.
ICC requires that our self-drilling screws have at least 3 threads protruding through the steel deck panel to be considered properly installed.
Perhaps a better fastener in this situation would be a spring steel clip such as the ADOC14 or VOH14 as these do not require penetration into the purlin structure.
ANSI is an acronym for American National Standards Institute.
ANSI is a private non-profit organization that administers and coordinates the U.S. voluntary standardization and conformity assessment system. Its mission is to enhance U.S. global competitiveness and the American quality of life by promoting, facilitating, and safeguarding the integrity of the voluntary standardization system. ANSI is the official U.S. representative to the International Accreditation Forum (IAF), the International Organization for Standardization (ISO) and, via the U.S. National Committee, the International Electrotechnical Commission (IEC). ANSI currently has offices in New York City and Washington, DC.
ANSI serves as administrator and coordinator of the United States private sector voluntary standardization system.
The Institute oversees the creation, promulgation and use of thousands of norms and guidelines that directly impact businesses in nearly every sector.
ICC is an acronym for International Code Council.
The ICC-ES was founded in 1994 as a nonprofit organization dedicated to developing a single set of comprehensive and coordinated national model construction codes. The founders of the ICC are Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO), and Southern Building Code Congress International, Inc. (SBCCI). Since the early part of the last century, these nonprofit organizations have developed the three sets of model codes used throughout the United States. ICC follows ANSI norms guidelines (standards).
ICC-ES reports are what most structural engineers use when specifying fasteners and materials for jobs.
In essence, ICC-ES takes the appropriate standards written by ANSI and works out a testing program for a product; then applies industry safety-factor standards (calculations) to the test results. Finally, ICC-ES performs factory inspections to make certain that proper quality control standards are being applied.
This makes it convenient for engineers who need to spec a product, as they can trust that the values given in an ICC-ES evaluation report follow industry standards for quality and safety .
Required tools and fasteners: ODM, ODM375, ODM916, TE-12, Torque Wrench, 3/8” Wedge Anchor, HOCL-45 Angle Clip, ceiling wire.
Step 1. Drill a 3/8” hole into the concrete ceiling using an ODM (Overhead Drill Machine) fitted with an ODM375 3/8”x 3.325” HALT bit.
Step 2. Remove the ODM375 HALT bit and insert an ODM916 SDS Plus 9/16 ” socket adapter, set the hammer drill to hammer only.
Step 3. Insert a 3/8” wedge anchor with a HOCL-45 angle clip prettied to ceiling wire into the ODM916 socket adapter.
Step 4. Raise the ODM up to the hole and insert the wedge anchor using the hammer function of the hammer drill.
Step 5. Use a TE-12 extension pole equipped with a LMP 9/16 Hex Plug to tighten the 9/16” nut on the wedge anchor to the appropriate torque using a torque wrench (Usually 25 ft/lbs).
Inspiration for this tool came from watching a friend pre-wrap thousands of wires onto purlin clips, day after day in his shop. I thought to myself, there has got to be a faster and easier way to attach ceiling wire onto joists without the hassle of having to pre-wrap the wire.
Our solution is the PurlinMaster, a multi-purpose pole tool that allows you to install a purlin clip and then wrap ceiling wire to the clip using the same tool, all from the safety of the ground. This effectively eliminates the need for costly scaffolding and scissor lifts. No longer will you have to purchase and haul around messy pre-wrapped ceiling wire. Instead, hang and wrap on an as-needed basis.
The PurlinMaster is actually part of a proprietary system from Doc’s Industries Inc., which offers its own line of purlin clips designed to work with the PurlinMaster as well as traditional installation tools.
Past installation systems required the ceiling wire to be wrapped onto the clip before installation. The PurlinMaster system represents a major innovation in the installation of ceiling wire to purlin joists. It makes installing purlin clips as easy as installing ceiling wire with an eye lag screw. An added benefit to this tool is that the clip will not “pop off” as the clip is safely protected inside the head during installation.
The concept behind the PurlinMaster is a unique twist on the traditional eye lag pole, a tool that has been utilized by acoustical ceiling contractors for decades. In fact, the PurlinMaster even comes with an interchangeable head that converts the tool into a standard eye lag pole in seconds. This allows you switch from installing purlin clips to installing wood screws at a moment’s notice. There are several other interchangeable heads available for hanging threaded rod and jack chain, in addition to many other applications (sold separately).
The PurlinMaster requires the use of Doc’s™ proprietary purlin clips. Take a moment to watch the video found in the link below and you will see how easy it is to hang ceiling wire from z purlin or bar joists using this tool. http://www.purlinmaster.com
The PurlinMaster works with Doc’s™ ADOC14 “Z” purlin clip as well as Doc’s™ VOH14 “C” purlin clip. These clips install easily and are compatible with traditional installation tools like the Caddy® VAFT, Ramset® J-Master & Doc’s™ HOIT-AL tools.
Installation is completed in a handful of easy steps. Start by inserting a clip into the head of the PurlinMaster. Then thread the ceiling wire through the clip. Stand in front of the purlin joist and position the clip above the joist. Pull down on the pole, locking the teeth of the clip onto the joist. Then walk forward, pushing up to release the clip. Lower the pole down a couple inches, trapping the wire inside the ring. Now simply twist the wire onto the clip, just as you would twist wire on to an eye lag screw. No need to pre-wrap the wire onto the clip!
Doc’s LS-6-3660 style extension pole was designed for use with both Hilti’s DX 36 and Ramset’s D-60.
The D-45 is essentially the same tool as the D-60, only with a shorter pin capacity.
In the United States, most suspended ceilings are fastened to poured concrete decks using a powder actuated tool attached to an extension pole. An extension pole allows the installer to stay on the floor and avoid dangerous ladders or expensive scissor lifts. They also cut down on time and improve efficiency.
There are several manufacturers of powder actuated tools used in the suspended ceiling industry: Hilti, Ramset, Powers, Simpson and Bluepoint. The Hilti DX 350 powder actuated tool (PAT) and its cousin the DX35 has been the standard of the industry for many years. Most of the other manufacturers began making similar tools (knock offs) when Hilti’s patent expired. The extension poles offered by these manufacturers can be more expensive than the powder actuated tool itself. Luckily there are other companies making extension poles. The Long Shooter brand of pole tools for instance has a proven track record of high quality and is available at a low cost.
Typically an extension pole consists of a fiberglass pole with a means to secure the PAT tool on one end and a trigger pull on the other. The installer has to be protected from shock in case an electrical conduit is pierced by the PAT nail. Therefore, PAT extension poles are usually made of fiberglass and have a dielectric coupling to withstand up to 10,000 volts.
Ceiling wires pre-wrapped to an angle clip and a concrete pin are available at some of the larger distributors. Pre-wrapped ceiling wire assemblies coupled with an extension pole allow a single worker to install 700 or more ceiling wires in an average day. Most contractors customize their pole tool by attaching a short section of electrical conduit or PVC pipe to the side of the pole. This is used to hold a number of ceiling wire assemblies to cut down on trips back and forth to re-stock.
Ramset’s Viper tool was developed specifically for the suspended ceiling industry in the US. Early versions of Ramset’s Viper tool did not require a trigger-pull mechanism. Instead, the tool was pressed against the ceiling and the impact or “BUMP” activated the tool. This “BUMP” feature allowed the tool to be place on a simple and inexpensive telescoping pole. The latest version of the Viper, the Viper4, requires a trigger pull mechanism and a special extension tool. The Viper 4 is not a “BUMP” tool.
Powers Fasteners makes a “BUMP” tool similar to the older versions of the Viper. Powers calls their tool the Sniper. Most fans of the “BUMP” tool are switching to the Sniper.
In summary, extension poles for powder actuated tools increase efficiency, improve safety and greatly reduce cost. There are videos on-line that demonstrate how PAT tools are mounted to extension poles, as well as how they’re used.
Eye lag screws have long been used in commercial construction to provide an economical and fast way to hang things over head. If you need to suspend something from a wood or sheet metal ceiling, you should consider the eye lag screw.
The acoustical suspended ceiling industry uses eye lag screws almost exclusively to hang ceiling wires. They are economical and can be installed quickly and safely from the floor. These screws can be used in many other overhead applications. Such as hanging lights, signs, electrical cable, data communications cable (CAT5 and CAT6), HVAC ducts, electrical conduit, electrical trapeze, shielded cable and telephone wire to name a few.
Description and load limits:
The eye of the screw is a 3/16” hole punched in the flattened area. The flat end is used to twist the screw in. Screws designed for wood applications are about three inches long and have about an inch and a half of coarse threads that taper to a sharp point; here is no need to pre-drill a pilot hole. Pull out strengths vary with penetration and wood strength, but are usually more than the strength of the ceiling wire (600 pounds). Screws designed for sheet metal are case hardened and zinc plated. They may have a sharp point (for thinner gauges) but usually have a drill point. Pull strength in sheet metal varies with metal thickness. Typically the thinner gauges (22 gauge) are allowed loads of 120 pounds. The thicker gauges (18 gauge) are allowed loads of around 240 pounds.
Methods of installation:
Telescoping pole tools are available that will reach a ceiling of up to 30’. These eye lag extension poles allow you to drive in an eye lag screw and “twist” off the ceiling wire from the ground. There are installation videos available on-line that demonstrate how easy these poles are to use. The LagMaster Plus is the most versatile of the eye lag poles available for this purpose, as it can also be used to hang threaded rod, jack chain and spring steel clips from the ground. In some areas like California, eye lag screws pre-wrapped to ceiling wire are available. These pre-wrapped screws are used to make installation of ceiling wire even faster and to satisfy code requirements for hospitals, jails and schools.
When you are up next to the ceiling, you can use a drill driver jig to twist in the screw. This is the method used when you only have a few screws to install. This would typically require a ladder, scissor lift or scaffolding.
In summary, eye lag screws are surprisingly strong and versatile, whether you’re fastening to a wooden joist or metal decking. While designed to suspend ceiling wire, they can be used to hang just about anything within weight specs.
Drilling overhead into concrete can be grueling and exhausting work. It’s not surprising that several companies have come up with special machines and devices to keep the operator on the ground and to make this arduous job a little easier. One of the least expensive and most innovative of these tools is the Overhead Drill Machine (ODM).
All concrete anchors require holes. So if you want to attach a hanger or secure something to a concrete ceiling overhead, drilling into concrete is a fact of life. Traditional methods include climbing a ladder with a hammer drill, setting up scaffolding or renting a scissor lift. Fatigue and muscle strain from repeatedly drilling overhead can lead to injury to the neck, back and shoulders. Safety should always be a major concern when an operator is performing a strenuous and labor intensive job for long periods of time.
Several patents have been filed dating back to 1984 for machines like “overhead drill jig” and “Jig assembly for drilling vertically upward”. There was even a University of California study funded through national labor and safety grants. As a result, there are several machines being marketed. These machines are designed to drill holes from ¼” to ¾” in diameter for commercial building trades (fire sprinklers, HVAC, electrical, plumbing, suspended ceilings and data communications).
The most expensive of these tools comes with a special drill cradle, a mobile base, a winch system to push the drill against the ceiling and a vacuum system to reduce dust. There is one model that drills two holes at once, a set distance apart. These tools are bulky and require preparation and planning to set up. However, they definitely make the job less onerous. These tools retail from around $2,000 to $3,500.
A less expensive alternative places the hammer drill at the end of a telescoping pole, which is then lifted to the ceiling by hand or with a foot pedal. These tools were designed to fasten suspended ceiling wires to concrete ceilings in Canada on jobs where powder actuated tools are restricted. They have proven to be versatile and commercial grade, able to withstand the punishment of high volume jobs.
The most economical of the telescoping poles uses a ceiling probe to switch the hammer drill on and off. As the probe is depressed against the ceiling, it pushes the trigger of the hammer drill, thereby activating the trigger. This mechanism eliminates the need for a remote switch and allows the operator to hold the tool securely with both hands.
Beware of tools that do not place the hammer drill directly against the ceiling. Hammer drills are engineered to impact and rotate a carbide bit at a speed that drills a hole efficiently in hard concrete. When you put a long extension between the hammer drill and the ceiling, you lose efficiency and will eventually destroy the extension tool.
