Through-the-fixture installation is supported. The AWA-37-350 wedge anchor is made so it can be driven through the mounting hole in the fixture and into the drilled hole in the concrete beneath, so a strut bracket, conduit clamp or pipe hanger can be held in place and anchored in one pass instead of setting anchors first and trying to line the fixture up afterward.

Yes, the AWA-37-350 carries a UL Listed mark on its spec record. That matters on electrical work where the inspector is checking that the support hardware under conduit and cable tray is listed, not just the raceway itself.

A wedge anchor like the B-Line AWA-37-350 is a mechanical expansion anchor for solid concrete, and it is rated here for heavy and medium duty all purpose work, which covers strut channel, trapeze hangers and conduit supports off a poured deck or wall. It is not the part for hollow block, drywall or a suspended metal deck, those need a toggle or a sleeve type designed for hollow base material. For solid concrete where you want to set the fastener through the fixture, this is the type.

The AWA-37-350 is zinc plated carbon steel. Zinc plating is a mild corrosion coating suited to dry interior work, so it is fine in conditioned buildings and typical electrical rooms. For exposed exterior, wash-down, coastal or chemically aggressive locations, specify a stainless or hot dip galvanized wedge anchor instead of the zinc plated version.
