B-Line B22SHA-120YZN Eaton series strut back-to-back welded channel, 1.62" channel height, 120" channel length, 1.62" channel width, Steel, 12 Gauge, SHA hole pattern, B22 channel type, Yellow zinc chromate

B22 is a back-to-back welded channel, meaning two channel sections are welded together spine to spine to form a closed box profile. The B-Line B22SHA-120YZN measures 1.62 inches in height and 1.62 inches in width, so you get open slots on two opposite faces instead of one. Use it where a single channel would deflect too much: long trapeze runs, pipe racks, and free-standing structural frames. For a simple wall-mounted strip or light conduit support, a single-depth channel is lighter and cheaper to hang.

Yellow zinc chromate is a plated indoor finish. It holds up fine in dry interior electrical rooms, mechanical spaces, and concealed ceilings. For exterior work, wash-down areas, parking structures, or anywhere it sees weather or chemicals, specify hot-dip galvanized or stainless channel instead. The B22SHA-120YZN is supplied in yellow zinc chromate over steel.

SHA is B-Line's designation for a slotted hole pattern punched into the channel, as opposed to solid (unpunched) channel. The B22SHA-120YZN carries that pattern, which lets you bolt through the back of the channel for wall or structure attachment anywhere along the 120 inch stick instead of drilling on site. If your detail calls for solid channel with no back holes, this is not the part number to order.

No. The B22SHA-120YZN is supplied as bare channel only, 120 inches long. Spring nuts, hardware, end caps, post bases, braces, and any closure strip are ordered separately, so build those into your takeoff before the crew shows up.
