B-Line B54SHA-240GRN Eaton series strut back-to-back welded channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 14 Gauge, SHA hole pattern, B54 channel type, DURA GREEN

The B54 channel is 1.62 in wide, which is the narrow (1-5/8 in nominal) strut profile, so hardware sized for 1-5/8 in channel matches the slot opening. The .81 in height puts it in the shallow half-height family rather than the 1-5/8 in deep section, so check that any spring nut or clamp you pair with it is rated for shallow channel depth.

Back-to-back welded means two channel sections are joined along their backs and welded into one member, so you get open slots facing both directions off a single piece. Electricians use that where trapeze hangers, conduit racks, or equipment supports need to pick up hardware on both faces instead of running two separate sticks and bolting them together. If you only ever clamp on one side, a single B54 channel does the job with less weight; this welded assembly runs 36.4 lb over its 240 in length.

The channel is supplied with the SHA hole pattern punched in, so it is pre-drilled rather than solid back. That matters when you are anchoring to deck, wall, or threaded rod and want to bolt through without field drilling 14 gauge steel. If your detail calls for a solid, unpunched back, this is not the part.

Order by the full catalog number B54SHA-240GRN: B54 is the channel type, SHA the hole pattern, 240 the length in inches, and GRN the DURA GREEN finish. Change any one of those segments and you get a different stick, so give a distributor the complete string rather than just "B54 strut."

DURA GREEN is Eaton B-Line's green coating over the steel channel, used where a plain or plated strut would not hold up and where the green color is specified for identification across a facility. If your job was built with green Dura coated strut on other runs, this matches that system; if the drawings call for hot dip galvanized or pre-galvanized, order that finish instead.

At 36.4 lb over 240 in it is a two-man carry in practice, mostly because of the length rather than the weight. It is 14 gauge steel and cuts with a bandsaw or chop saw to whatever lengths the run needs; field cut ends lose the factory DURA GREEN coating, so touch them up if the run is exposed.
