B-Line B22A-240YZN Eaton series strut back-to-back welded channel, 1.62" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, B22 channel type, Yellow zinc chromate

B22A is two lengths of B22 channel welded back to back, so you get slots facing both directions on one member. The B-Line B22A-240YZN is 12 gauge steel, 1.62 in by 1.62 in, in a 240 in length. Use single channel when you only need to mount off one face; use the back-to-back welded section when you need to attach on opposing faces, such as a trapeze with hangers above and supports below, or where you want the added stiffness of a doubled member on longer spans.

Yes. B22A is built from B22 channel, which uses the same 1-5/8 in nominal profile hardware as standard B-Line strut, and the section measures 1.62 in across the face. Channel nuts, straps, clamps, and angle fittings sized for 1-5/8 in strut engage the slot normally. Fittings and hardware are ordered separately.

Yellow zinc chromate is a plated finish intended for dry indoor use, mechanical rooms, and covered interior runs. For exterior, rooftop, parking structure, or washdown work, specify hot dip galvanized or stainless strut instead; the plating on the B22A-240YZN will not hold up to standing water or chlorides long term.

Order it as Eaton B-Line B22A-240YZN: B22 channel type, welded back to back, steel, 12 gauge, 1.62 in height by 1.62 in width, 240 in long, yellow zinc chromate finish.

Yes, it is normally field cut to length with a bandsaw, chop saw with a metal blade, or portaband. Cutting 12 gauge steel leaves bare edges, so on this yellow zinc chromate material touch the cut ends and any drilled holes with a zinc rich paint to keep rust from starting.
