B-Line B52SH-240HDG Eaton series strut channel, .81" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, SH hole pattern, B52 channel type, Hot-dipped galvanized

B52 is the shallow profile. The channel measures .81 in in height with a 1.62 in width, so it is roughly half the depth of a standard 1-5/8 by 1-5/8 channel while keeping the same 1-5/8 nominal opening width. That means standard strut nuts and fittings sized to the 1-5/8 inch opening still engage, but you get less section depth and a lower stand-off from the wall or deck.

The finish is hot-dipped galvanized over 12 gauge steel, which is the finish specified for exterior runs, parking structures, tunnels, and washdown or damp interiors where plain or pre-galvanized strut would rust at the cut edges. For dry indoor electrical and mechanical support, a pre-galvanized channel is the usual lower-cost choice.

Yes. The channel is 1.62 in wide, which is the standard 1-5/8 inch strut opening, so 1-5/8 inch spring nuts, channel nuts, and clamps seat in the lips the same way they do on deeper channel. Only the depth changes at .81 in, so anything sized by the opening still fits.

SH is the slotted hole pattern punched in the back of the channel, so you can bolt the strut straight to a wall, deck, or steel member without drilling on site. If you want an unpunched back for a continuous run, that is a different hole pattern part number, not this one.

Order B-Line B52SH-240HDG. That breaks down as B52 channel type, SH hole pattern, 240 in length, HDG for hot-dipped galvanized. Change any one of those and the part number changes, which is how you specify a different length or a plain finish from the same family.
