The B-Line AWA-50-275 wedge anchor can be installed through the fixture, so you drill the hole with the bracket, strut, or clip already in position and drive the anchor straight through the mounting hole. That saves a layout step on overhead concrete work and keeps hole alignment honest when you're hanging strut or pipe supports.

Yes, the AWA-50-275 all purpose anchor is UL Listed, which is what inspectors look for when the anchor is carrying conduit, cable tray, strut, or luminaire loads on an electrical job.

The anchor is 2-3/4 inches long overall, so your hole in the concrete has to be drilled deeper than the embedment portion that goes below the fixture. Subtract the thickness of whatever you are fastening (bracket, strut, base plate) plus the nut and washer stack from that 2-3/4 inches to see how much embedment you actually get, and drill deeper than that so drill dust and spoil have somewhere to go.

Zinc plated carbon steel is a dry-interior and lightly protected finish. It is fine for indoor slabs, mechanical rooms, and ceilings, but in a wet vault, a washdown area, a coastal exterior, or anywhere chlorides are present the plating gives up and the carbon steel body corrodes. Specify a stainless wedge anchor or a hot dip galvanized anchor for those locations instead.

A wedge anchor like the AWA-50-275 is the faster choice when you can install through the fixture: drill, drive, tighten the nut, done, and the stud stays sticking out for the nut and washer. A drop-in anchor is the one to pick when you need a flush hole and a threaded rod that can be removed and reinstalled later, or when the fixture has to sit tight to the slab with no protruding stud. For routine overhead strut and conduit support in solid concrete, the wedge anchor is the normal call.

It is classed as a heavy and medium duty all purpose anchor, so it covers general concrete fastening across both load ranges rather than being a light duty shelf or trim anchor. It weighs .19 lb each, which is useful when you are pricing out a box quantity for a shipment or a job cart.

Order it as Eaton B-Line model AWA-50-275, from the 275 wedge anchor series. That is the number to quote if you are matching anchors already set on a job so the whole installation uses one fastener type.
