B-Line Eaton series strut back-to-back welded channel, 1.62" channel height, 240" channel length, 1.62" channel width, Aluminum, 12 Gauge, B22 channel

Yes. The channel is 1.62 inches wide and 1.62 inches tall per side, which is the nominal 1-5/8 inch strut profile, so the usual 1-5/8 inch spring nuts, channel nuts, pipe clamps, post bases, and angle fittings seat in the slot normally. Because it is welded back-to-back, you get a usable slot on both faces for mounting in two directions off one member.

The B22A-240AL is aluminum rather than steel, so it does not rust and needs no galvanizing or paint touch-up at cut ends. That makes it the pick for wet, washdown, coastal, or chemically aggressive areas, and for exposed exterior runs. The trade-off is that aluminum carries less load than steel of the same 12 gauge section, so if you are hanging heavy pipe on wide spans, size the span accordingly.

Order Eaton B-Line part number B22A-240AL. The suffix reads out as B22 back-to-back channel, aluminum, 240 inch length. If you need the same profile in a different stick length or in steel, the base B22 designation stays the same and the length and material suffix changes.

Yes, and it is normally bought long and cut. Aluminum cuts fast with a chop saw and a non-ferrous blade, and unlike steel strut there is no coating to burn off or cold-galvanize at the cut. Ordering the 240 inch stick rather than shorter pieces lets you get several trapeze hangers or uprights out of one length with less scrap.
