B-Line Eaton series strut channel, Strut channel, Stainless Steel AISI type 316

Yes. It is a stainless steel channel, which is what you specify for exterior runs, rooftops, coastal air, wastewater plants, food processing, and other washdown areas where plain pre-galvanized strut corrodes. Keep the whole assembly consistent: pair it with stainless channel nuts, fittings, and threaded rod, since mixing plain steel hardware onto stainless channel puts the corrosion right back at the connection points.

UL Listed, yes. That matters for conduit racks, cable tray supports, and equipment mounting where an inspector wants listed support components on an electrical installation. It is catalogued as electrical mounting hardware, and the 1-5/8 in profile is what conduit clamps and trapeze hangers are built around.

No. This is the channel only, a single 240 in stick. Anchors into the deck or wall, spring nuts, end caps, conduit clamps, splice plates, and any fittings are ordered separately. For a stainless run, specify stainless versions of all of those so the fasteners match the channel.

Shallow channel like the B52SH, at .84 in high and 1.625 in wide, is the choice when you need the standard 1-5/8 in fitting width but not the load capacity or the projection of a full-depth section: light conduit runs, small device and box mounting, wall-mounted racks in tight plenums, and anywhere the channel sits close to a finished surface. Step up to full-depth channel for trapeze hangers carrying heavy conduit banks, cable tray, or long unsupported spans, where the deeper section is doing the work.
