B-Line Eaton series strut back-to-back welded channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, SHA hole patter

The B52 channel comes hot-dipped galvanized, which is the finish normally specified for exterior runs, rooftops, parking structures, and damp mechanical spaces. It's 12 gauge steel under the zinc, so cut ends should be touched up with a cold galvanizing compound after field cutting.

SHA is B-Line's designation for a slotted hole pattern punched in the channel back, so you can bolt the strut to structure or attach hardware without drilling on site. If your drawing calls for solid back (no punching) or a different punch series, SHA is not that part.

Back-to-back welded channel like the B52 doubles the section by joining two channels at their backs, so it carries longer unsupported spans and heavier loads than a single stick and gives you mounting slots on both faces. Use single channel where the run is short or only one face needs attachment; go back-to-back on long trapeze runs, seismic bracing, and multi-tier pipe racks.

Order Eaton B-Line part B52SHA-240HDG. The number breaks down as B52 channel type, SHA punch pattern, 240 inch length, HDG for hot-dipped galvanized finish.

No. It ships as bare channel only. Spring nuts, hardware, fittings, closure strips, and end caps are separate line items, so size those to the 1-5/8 inch strut profile when you build the order.

This one is 12 gauge steel, the standard heavy-duty thickness for structural strut work. Lighter gauges exist in the B-Line line for light utility runs, but for conduit racks, pipe trapezes, and equipment support 12 gauge is what gets specified.
