Yes, but only for nine named MGV16 soffit vent sizes, not the manufacturer's full current lineup.
California's Office of the State Fire Marshal lists Able Multi-Guard's soffit vents on its Building Materials Listing as 8165-2363:0002, active through June 30, 2027.
What that listing covers is narrow. The named MGV16 sizes share one construction: 26-gauge G90 steel, PROMASEAL-LFC strips, and 1/16-inch galvanized-steel mesh, tested to the same ASTM E2886 standard the listing cites. Five of them carry an asterisk in the published text, and the listing gives no legend for what that mark means. Whatever it flags, a specifier reading the document alone will not find out.
That gap matters because the manufacturer's current catalog goes well beyond what was tested. It now includes alternate sizes, 1/8-inch mesh, and galvalume, copper, stainless steel, and aluminum versions, none of which appear in this listing. Only the named MGV16 models, in the steel, strip, and mesh combination above, are covered.
For a soffit going into a wildfire-rated house, the listing is the standard to build to, not the catalog page. Model, opening size, orientation, louver or strip construction, mesh, fasteners, perimeter sealant, free area, and installation instructions all need to match the current data sheet, and the listing itself is only good through June 30, 2027. After that date, or for anything outside these named sizes, it stops answering the question.
