B-Line B22SH-240BSYZN Eaton series strut channel, 1.62" channel height, 240" channel length, 1.62" channel width, 12 Gauge steel, SH hole pattern, B22 channel type, Yellow zinc chromate

SH is the slotted-hole pattern, so the back of the channel comes punched rather than solid. That lets you bolt the channel directly to studs, deck or concrete anywhere along the run without field drilling, and the slots give some adjustment when your anchor points do not line up. If you want an unpunched back for a cleaner trapeze or a solid welded run, order the plain B22 instead of the SH version.

Yellow zinc chromate is a plated finish meant for dry interior service, mechanical rooms, electrical rooms and covered spaces. It is not a hot dip galvanized or stainless finish, so it should not be run outdoors, in wash-down areas or in corrosive process environments. For those openings choose a hot dip galvanized or stainless B22 section.

The stick ships as bare channel only. You still need strut nuts sized for 1-5/8 inch channel, bolts or threaded rod with washers, and whatever fittings the layout calls for, angle brackets, pipe clamps, post bases or beam clamps, plus anchors for the structure. End caps are a separate item if you want the cut ends covered. The SH punching means you can bolt the channel back to structure without drilling it first.

B22 is a single 1.62 by 1.62 inch channel with one open slot, 12 gauge steel. It is not the back-to-back welded double section, so you get one usable channel face per stick. For trapeze hangers carrying heavier conduit banks where deflection matters, spec the deeper or doubled profiles instead.

12 gauge is the standard structural weight for 1-5/8 inch strut and is what most conduit racks, trapeze hangers and equipment supports are built from. Lighter 14 and 16 gauge channel is the reduced-duty option. Span between supports still governs the load you can hang, so lay out your hanger spacing to the engineer's detail.

Order it as Eaton B-Line B22SH-240BSYZN. That breaks down as B22 channel type, SH slotted hole pattern, 240 inch length, and YZN for the yellow zinc chromate finish.

Yes, 12 gauge steel channel cuts with a bandsaw, chop saw with a metal blade or a portaband, and a 240 inch stick is normally cut to length in the field. Cut ends lose the plated coating, so hit them with a cold galvanizing or zinc-rich touch-up if the run matters to you, and deburr before sliding nuts in.
