B-Line Eaton series strut channel, 3.25" channel height, 240" channel length, 1.62" channel width, Steel, 12 Gauge, S hole pattern, B11 channel type,

The B11 is a deep single channel, 3.25 inches high by 1.62 inches wide. That 1.62 inch width is the standard 1-5/8 inch strut face, so ordinary 1-5/8 strut nuts, clamps and fittings land on it. The extra height is depth of section, not two channels welded together, so it gives more span capability than a 1-5/8 x 1-5/8 channel while still taking the same hardware on the open face.

S is the slotted back pattern: the channel back carries a repeating run of slots rather than being solid or knockout-punched. It lets you bolt the channel to a wall, deck or another piece of strut anywhere along the run without drilling, and it lets threaded rod or conduit hangers pass through. If you want an unpunched back for a cleaner appearance or maximum strength, that is a solid-back channel instead, not the S pattern.

Pre-galvanized steel is a mill-coated finish intended for dry interior and protected locations. It handles normal indoor mechanical rooms, ceilings and equipment racks fine. For exposed exterior work, wash-down areas, or a deck exposed to road salt and freeze-thaw, specify hot-dip galvanized after fabrication or stainless instead, because cut ends on pre-galvanized stock are bare steel and will start rusting.

Yes. The open face measures 1.62 inches, the nominal 1-5/8 inch strut width, so spring nuts, channel nuts, pipe straps, beam clamps and fittings made for 1-5/8 inch strut engage the return lips normally. What changes with the B11 is the depth behind the face, 3.25 inches, so check clearance where the channel passes close to a wall or deck.

12 gauge steel is the standard heavy-duty strut thickness used for trapeze hangers, conduit racks and equipment supports, and on the B11 it is paired with a 3.25 inch section depth, which is what buys you span between supports rather than the gauge alone. Lighter 14 and 16 gauge channel is for light fixture and small-pipe support. For the actual allowable load on your span and spacing, work to the manufacturer's load table for the B11 section.

Order Eaton B-Line B11S-240GLV. Read it as B11 channel section, S slotted hole pattern, 240 inch length, GLV pre-galvanized finish. Quote that full string when matching an existing run, since the same B11 section is also made in other lengths, hole patterns and finishes.

No. B11S-240GLV is bare channel only, one 240 inch stick of 12 gauge pre-galvanized steel. Strut nuts, hex bolts, end caps, splice plates, brackets, pipe clamps and any threaded rod for the hangers are all separate line items, so build them into the order before the crew is on site.
