B-Line B32SH-120GRN Eaton series strut channel, 1.37" channel height, 120" channel length, 1.62" channel width, Steel, 12 Gauge, SH hole pattern, B32 channel type, DURA GREEN

It's the shallow B32 profile: 1.37 inches high by 1.62 inches wide, in a 120 inch stick. That's the half-height channel, not the deeper 1-5/8 by 1-5/8 section. If your drawing calls for full 1-5/8 inch depth for heavier trapeze loads, this isn't the piece, but standard 1-5/8 inch wide strut nuts and fittings still ride the same 1.62 inch opening.

The channel opening is 1.62 inches wide, the common 1-5/8 inch strut dimension, so hardware sized for 1-5/8 inch channel seats in it. Watch the depth instead: at 1.37 inches overall height the B32 is a shallow section, so deep spring nuts and fittings built for the full 1-5/8 inch deep channel can bottom out. Pick nuts and straps rated for the shallow profile.

SH is the slotted-hole back pattern, so the channel comes punched along the back wall rather than solid. You get bolt-through points for mounting to structure without field drilling, and the slots give you some adjustment when your anchor layout doesn't land on centers. If you want an unpunched back for a cleaner look or full-section strength, order the solid-back version of the B32 instead.

DURA GREEN is Eaton B-Line's green coating over the 12 gauge steel channel. It's the standard painted finish used on interior electrical and mechanical support work. For wet exterior runs, corrosive process areas, or anywhere a spec calls for hot dip galvanizing or stainless, order the channel in that finish rather than relying on a painted coating.

16.2 lb for the full 120 inch stick. That's light enough for one person to carry and set overhead, which is part of why the shallow B32 section gets used for conduit racks and light trapeze hangers where a full-depth channel would be overkill.

12 gauge is the heavy-duty wall thickness for this style of steel channel, the usual choice where the run carries conduit banks, pipe, or equipment rather than just light signage. Thinner 14 and 16 gauge channel exists for light-duty support. Since B32SH-120GRN is the shallow 1.37 inch profile, the gauge is doing the work here, so don't substitute a lighter wall to save weight.

No. The part number B32SH-120GRN covers the 120 inch channel stick alone. Strut nuts, spring nuts, end caps, post bases, beam clamps, conduit straps, and the anchors or threaded rod to hang it are all ordered separately. Plan the fitting count before you order the channel so the run doesn't stall on the job.
