B-Line B12A-120GRN(MIG) Eaton series strut back-to-back welded channel, 2.43" channel height, 120" channel length, 1.62" channel width, Steel, 12 Gauge, B12 channel type, DURA GREEN

Yes. The B12 channel profile is 1.62 inches wide, the standard 1-5/8 inch strut opening, so spring nuts, channel nuts, clamps and fittings sized for 1-5/8 inch strut engage the turned-in lips normally. The back-to-back section simply gives you two usable faces for that hardware.

Back-to-back welded channel gives you strut faces on both sides and far more stiffness over a span than a single stick. Use it for trapeze supports carrying heavy conduit racks, long unsupported runs, and posts or uprights where a single 1-5/8 inch channel would deflect. If you are hanging light conduit at close spacing, single channel is the cheaper and lighter choice.

It is 12 gauge steel, which is the heavy-duty strut thickness rather than the 14 or 16 gauge used for lighter support work. Combined with the welded back-to-back section, that is what you want under seismic bracing, pipe racks and heavier mechanical loads.

DURA GREEN is Eaton B-Line's green coating on the steel channel. It is a painted-type protective finish suited to indoor and covered industrial environments. For direct outdoor exposure, wet process areas or corrosive atmospheres, specify hot dip galvanized or stainless channel instead.

The B12A-120GRN is the channel only. Budget separately for channel nuts and bolts, beam clamps or post bases, threaded rod for trapeze hangers, end caps, and pipe or conduit clamps. Touch-up paint is worth having on hand since field cuts expose bare steel.

Order Eaton B-Line B12A-120GRN(MIG). B12 is the channel type, 120 is the length in inches, GRN is the DURA GREEN finish, and MIG denotes the welded construction. Quoting the full string avoids getting a plain single channel or a different finish.
