B-Line Eaton series fastener hardware and accessories, Heavy and medium duty all purpose anchor, Stainless steel,3⁄8" x 3-3⁄4", Anchors can be install

It's made of stainless steel, which is the material you want for exterior rooftop equipment supports, wash-down areas, coastal work, and damp mechanical rooms where a plated carbon steel anchor would rust. If the job is dry interior concrete, a zinc-plated wedge anchor of the same 3/8 x 3-3/4 size does the same mechanical job.

Yes, the AWA-37-375SS carries a UL Listing, which is what inspectors look for when the anchor is carrying conduit racks, cable tray, strut, or luminaire supports. That's the reason it shows up on electrical submittals rather than a generic hardware-store anchor.

Yes. This anchor is built to be installed through the fixture, so you set the strut channel, bracket, or base plate in position, drill through its mounting hole into the concrete, then drive the anchor home and tighten. No transferring hole layouts, no chasing a misaligned bolt pattern.

A wedge anchor is a mechanical expansion anchor for solid concrete: as you torque the nut, the cone pulls into a clip that wedges against the hole wall. The AWA-37-375SS is rated by B-Line as a heavy and medium duty all purpose anchor, so it suits conduit racks, tray supports, equipment bases, and strut hangers in poured concrete. It is not the right choice in hollow block, brick, or drywall, where a sleeve, toggle, or screw anchor is called for, and it is permanent once set, so use a drop-in or threaded insert where you expect to remove the fixture.

Total length is 3-3/4 inches. Whatever embedment you set into the concrete comes out of that figure, and the remainder is what is left protruding for the fixture thickness, washer, and nut. For thicker base plates or stacked strut, step up to a longer 3/8 anchor rather than shorting the embedment.

Specify B-Line part number AWA-37-375SS, described as a 375SS wedge anchor, 3/8 x 3-3/4, stainless steel. That part number is what pins down both the stainless material and the 3/8 by 3-3/4 size, since B-Line's anchor line runs across several diameters and lengths in both plated and stainless.
