B-Line B22SHA-240GRN Eaton series strut back-to-back welded channel, 1.62" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, SHA hole pattern, B22 channel type, DURA GREEN

Yes. B22 is built from the standard 1-5/8 inch strut profile, and the opening measures 1.62 inches across, so ordinary 1-5/8 inch channel nuts, spring nuts, straps, and post bases seat in the slot. The difference from single channel is depth: because it is two sections welded back to back, the overall section is deeper than single strut, so through-bolts sized for single channel will be too short and you need longer bolts or hardware rated for double channel.

Single channel is the right pick when you are fastening flat to a wall, deck, or ceiling and only need hardware on one face. Go to back-to-back B22 when the strut has to stand on its own, span between supports, or carry loads from both sides, such as trapeze hangers, free-standing racks, and longer unsupported spans, because the welded double section is much stiffer about the bending axis than a single 12 gauge channel. On this part the section is 1.62 by 1.62 inches in 12 gauge steel.

SHA is B-Line's slotted hole pattern punched in the channel back, giving you adjustable fastening points along the run instead of having to drill. On the B22SHA-240GRN the pattern is present on the channel backs of the welded assembly, so you can through-bolt the strut to structure or bolt two runs together at regular intervals. If your spec calls for solid back (no holes), SHA is not the part to order.

DURA GREEN is B-Line's green painted coating on the steel channel. It is a paint finish, so it handles dry interior and sheltered service well but is not the choice for continuous exposure, washdown, or corrosive environments. For those, specify a hot dip galvanized or stainless B22 instead. The green colour is also commonly used to identify a particular service or trade on a shared rack.

Order Eaton B-Line part number B22SHA-240GRN. That breaks down as B22 back-to-back welded channel, SHA slotted hole pattern, 240 inch length, GRN for the DURA GREEN finish. Distributors quoting against a drawing should confirm the hole pattern letter, since B22 is also built plain and with other punchings.

It matches. The channel is 12 gauge steel, which is the standard heavy strut thickness called out on most electrical and mechanical support details, and in the back-to-back welded form you effectively have two 12 gauge walls at the base. If a submittal asks for a listing or agency certification on the channel itself, note that no certification is carried on this part.
