B-Line Eaton series strut back-to-back welded channel, 1.62" channel height, 240" channel length, 1.62" channel width, Steel, 14 Gauge, B24 channel ty

Yes. Each half of the B24A is standard 1.62 in (1-5/8 in nominal) channel, so the usual spring nuts, channel nuts, conduit clamps, beam clamps and fittings sized for 1-5/8 in strut engage the slots normally. Nothing special is needed because it is welded back to back.

Two channels welded back to back give you a closed box section with slots facing both directions, so you can hang or brace off either face and you get substantially more stiffness over a long span than one 1-5/8 in channel on its own. The B24A is the choice for trapeze mains, standoff posts and long unsupported runs; for a simple wall-mounted run of conduit or a short trapeze, single 1-5/8 in channel is lighter and cheaper to handle.

Pre-galvanized (electro or mill galvanized) steel is intended for dry interior and protected locations. It handles normal indoor humidity, mechanical rooms and above-ceiling runs fine, but for exterior, wash-down or corrosive environments you want hot-dip galvanized or stainless strut instead. Note also that cutting a 240 in stick to length exposes bare steel at the cut, which should be touched up with a zinc-rich coating.

Order Eaton B-Line part B24A-240GLV. The number breaks down as B24 channel type, 240 in length, GLV for pre-galvanized. There is one configuration, so no finish or length suffix has to be chosen separately.
