B-Line Eaton series strut back-to-back welded channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 14 Gauge, SHA hole patter

The B54SHA-240GLV channel is pre-galvanized steel, which is the standard finish for indoor and protected applications such as mechanical rooms, ceilings and interior wall runs. Pre-galvanized (mill galvanized) coating is thinner than hot-dip and the cut ends are left bare, so for exterior exposure, wash-down areas or corrosive environments you want a hot-dip galvanized or stainless channel instead.

SHA is B-Line's short-slot hole pattern, punched in the back of the channel so you can through-bolt or lag the strut to a wall, deck or structural steel without drilling on site. The slots also give a little adjustment when your anchor layout is not exact. If you want a solid back with no holes, that is a different channel designation, so specify carefully when matching an existing run.

Use the back-to-back B54 where you need fittings or clamps on both sides of the member, for example a trapeze carrying conduit on top and pipe hung below, or a freestanding rack where equipment mounts on either face. A single channel is the cheaper, lighter choice for a plain wall-mounted run or a short trapeze that only needs one working face. Note this B54 is the half-height profile at .81 in, not the full 1-5/8 in deep back-to-back section, so it is a shallower member.

Order Eaton B-Line B54SHA-240GLV. That single number carries everything that has to match on a repeat order: B54 back-to-back channel, SHA hole pattern, 240 inch length, and GLV for the pre-galvanized finish. If you are standardizing a building on one strut, that is the number to put on the spec sheet.

No. This is bare channel only, a 240 inch stick of 14 gauge pre-galvanized steel. Strut nuts, spring nuts, end caps, corner and wing fittings, threaded rod, beam clamps and anchors are all ordered separately. Budget hardware per connection point when you take off the job.

Yes, 14 gauge steel channel cuts cleanly with a bandsaw, chop saw with an abrasive or metal-cutting blade, or a portable band saw. Cut ends expose bare steel on pre-galvanized material, so touch them up with a cold galvanizing compound if the run is anywhere with moisture. Deburr before installing so strut nuts slide without hanging up.
