Question:
Your ICC-ES report lists two different holding values, ASD and LRFD. What do these two acronyms stand for?
Answer:
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.

Question:
Are the HOCL-1 and HOCL-45 angle clips ICC listed like other brands?
Answer:
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.
Appendix A
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:

We are sometimes asked if our HPH plastic composite J Hooks are certified safe for air handling (plenum) spaces.
The simple answer is YES.
HPH J Hooks have been tested and found to be in compliance with all UL criteria for support of conduit, tubing and cable (UL 2239). This includes compliance with UL 2043. UL 2043 is the standard for fire testing, which includes heat and visible smoke release of products installed in air handling spaces. Our certificate of compliance from UL is attached. The report includes the following paragraph:

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.

About ANSI:
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.
About ICC-ES:
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 .
