B-Line B54A-240GLV Eaton series strut back-to-back welded channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 14 Gauge, B54 channel type, Pre-galvanized

The B54 is a shallow, back-to-back welded profile: 1.62 in across the face, which is the familiar 1-5/8 in strut face width, but only .81 in deep. So slotted fittings, nuts and hardware sized to the 1-5/8 in face line up, while the depth is half that of a full 1-5/8 x 1-5/8 channel. If your drawing calls for the deeper section, the B54 is not the substitute.

Pre-galvanized is the finish on the B54A, which is a mill zinc coating applied to the steel before forming. It handles dry interior and sheltered service well. Cut ends and weld areas are bare, so for direct weather exposure, wet process areas or coastal air, spec a hot-dip galvanized or stainless channel instead.

Back-to-back welded channel is two channel sections joined along their backs, giving open slots facing both directions and a stiffer member than a single stick of the same face width. Electricians and mechanical contractors use it for trapeze hangers spanning longer runs, freestanding racks and equipment supports where you need to bolt fittings on opposite faces. For a simple wall-mounted run with hardware on one side only, a single channel is the cheaper, lighter choice.

No. The B54A-240GLV is the bare 240 in channel only. Channel nuts, brackets, end caps, beam clamps and threaded rod are all ordered separately, and they need to match the 1.62 in face width to seat in the slot.

Order by manufacturer part number B54A-240GLV. That designation breaks down as the B54 back-to-back channel type, 240 in length, and GLV for the pre-galvanized finish.
