B-Line Eaton series strut back-to-back welded channel, 1.62" channel height, 24" channel length, 1.62" channel width, Steel, 12 Gauge, SHA hole patter

B22 is a back-to-back welded channel: two standard channel sections welded back to back so the profile is closed rather than open on one side. On this piece the section measures 1.62 in by 1.62 in and it is formed from 12 gauge steel. Because it is a doubled section it carries more load and resists twist better than a single open channel of the same face width, which is why it gets used for trapeze hangers, standalone supports and longer unsupported spans.

Yellow zinc chromate is a plated indoor finish. It is fine for dry interior electrical and mechanical work, mechanical rooms, and concealed ceiling spaces. For exterior runs, parking structures, wash-down areas or corrosive environments, step up to hot dip galvanized or stainless strut instead; zinc chromate will bloom and rust in standing moisture.

Yes. The channel face is 1.62 in, which is the nominal 1-5/8 inch strut profile, so the usual 1-5/8 spring nuts, channel nuts, post bases, angle fittings and pipe clamps engage the lips normally. Being back-to-back welded, both faces accept fittings, which is the point of using B22 for trapeze and column applications.

SHA is B-Line's slotted hole pattern, punched in the channel face rather than a plain solid back. It lets you bolt through the strut anywhere along the run for hangers, brackets and threaded rod without field drilling. If your drawing calls for solid-back strut with no punching, SHA is not that part.

Single channel is the normal choice for a short trapeze between two rods. Go to the welded back-to-back B22 section when the span is longer, the load is heavier, or the member is standing on end as a post and needs stiffness in both axes. It is the same 1.62 in face so your fittings do not change, only the section depth and the amount of steel.

12 gauge steel, which is the standard structural strut thickness used for electrical and mechanical support work. Lighter 14 and 16 gauge strut exists for light-duty conduit and signage runs; if your spec sheet calls out 12 gauge, this is that material.

No. The B22SHA-240YZN is the channel only, a 24 inch cut length. Channel nuts, threaded rod, end caps, connector plates and any clamps for your conduit or pipe are ordered separately, so build that into the takeoff before the crew is on site.
