B-Line B32A-240GRN Eaton series strut back-to-back welded channel, 1.37" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, B32 channel type, DURA GREEN

Back-to-back means two B32 channel sections welded together along their backs, so you get openings facing both directions on one member. Use it where you need to hang or brace from two sides of the same run, or where a single stick of strut deflects too much over the span. For a straightforward wall-mounted trapeze or a short conduit run, a single channel is lighter and cheaper to handle. At 69.34 lb for a 240 inch piece, this one is a two-person lift.

Yes. The channel face measures 1.62 inches wide, which is the standard 1-5/8 inch strut profile, so the usual spring nuts, channel nuts, clamps, and fittings sized for 1-5/8 inch strut engage the lips. Height is 1.37 inches, the shallow (half height) B32 profile, so check any fitting that wraps the full section depth rather than just clipping into the slot.

DURA GREEN is Eaton B-Line's green painted coating over the steel channel. It is a coated finish rather than bare steel, so it handles normal indoor industrial and mechanical room conditions. For continuously wet, corrosive, or exterior exposure, a hot dip galvanized or stainless channel is the safer specification. Note the coating stops at the cut, so field cuts on a 240 inch stick should be touched up.

The B32A designation is the plain, unpunched version of the B32 back-to-back channel, so the web runs solid with no slot pattern. If you need field-adjustable bolt positions at fixed intervals, a slotted version of the same B32 profile is the one to order instead; otherwise you drill where you need it.

Order Eaton B-Line part number B32A-240GRN. The breakdown: B32 channel profile, A for the plain unpunched web, 240 for the 240 inch length, and GRN for the DURA GREEN finish. Changing the length or finish changes the suffix, so quote the full number when matching an existing run on site.
