B-Line B11A-240GRN Eaton series strut back-to-back welded channel, 3.25" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, B11 channel type, DURA GREEN

Yes. At 1.62 in wide the B11A uses the standard 1-5/8 in strut opening, so conventional spring nuts, channel nuts, clamps, and fittings sized for 1-5/8 in strut engage the returns on either face. Because the section is welded back-to-back, you can mount hardware on both sides of the run.

Back-to-back welded channel is two strut sections joined base to base, giving you an open slot on both faces and a much deeper section than a single 1-5/8 in profile. On the B11A it produces a 3.25 in overall height. Use it for long unsupported trapeze spans, heavy pipe or conduit racks, and free-standing supports where a single channel would deflect. For light single-run conduit clamps against a wall, a plain single channel is the cheaper and easier choice.

DURA GREEN is Eaton B-Line's green coating over the 12 gauge steel channel. It is a painted/coated finish rather than a hot-dip galvanized one, so it suits dry interior mechanical and electrical rooms and covered areas. For sustained outdoor exposure, wash-down, or corrosive process areas, specify a galvanized or stainless channel instead.

12 gauge is the standard heavy-duty strut thickness used for trapeze hangers and pipe racks, and the B11A doubles it up in a welded back-to-back section 3.25 in deep, which is what you go to when a single 12 gauge channel deflects over the span. Size the actual span and load against the engineer's load table for your job.

Order Eaton B-Line part number B11A-240GRN. That designation covers the B11 channel type, 240 in length, and the DURA GREEN finish in one number.

Yes, it ships as a 240 in stick of 12 gauge steel channel and is cut in the field with a band saw or abrasive chop saw like any strut. Cut ends expose bare steel, so touch them up with green or zinc-rich paint to keep the coated finish intact.
