Yes. The AWA-25-325SS is a through-fixture install anchor, so you can drill the hole through the mounting hole of the strut bracket, conduit clamp or channel, drop the anchor in, and tighten. No need to mark, remove the fixture, drill, and reposition.

It's a stainless steel wedge anchor, so it holds up better than zinc-plated carbon steel in wet, exterior, or corrosive environments like parking garages, rooftops, mechanical yards and wash-down areas. Stainless also avoids galvanic issues when you're mounting stainless or aluminum strut hardware.

Yes, the AWA-25-325SS carries a UL Listing. That matters on electrical work where an inspector wants listed components supporting raceway, cable tray, or luminaire hangers.

A wedge anchor is a one-piece stud that stays permanently in the hole; you drill, hammer it in, and torque the nut so the clip wedges against the concrete. It's for solid concrete only, not block or brick, and the stud sticks out afterward. A drop-in anchor sits flush and takes a removable bolt, which is what you want when the fixture has to come off later. The AWA-25-325SS is the wedge type, so plan on the threaded stud remaining in place.
