Canco MS Slotted Channel

Basic strut channel comes in the open box section 1+5⁄8 in (41 mm) square. A half height 1+5⁄8 in × 13⁄16 in (41 mm × 21 mm) version is also available, used mostly where mounted directly to a wall as it has significantly less stiffness and ability to carry loads across an open space or brace. A deep channel 1+5⁄8 in × 2+7⁄16 in (41 mm × 62 mm) version is also manufactured. The material used to form the channel is typically sheet metal with a thickness of 1.5 mm or 2.5 mm (12 or 14 gauge; 0.1046 inch or 0.0747 inch, respectively).[2] Several variations are available with different hole patterns for mounting to walls and supports. Solid channel has no holes predrilled, and must either be drilled on site or mounted in another fashion. Punched channel has round holes, large enough for an M16 or 5/8 inch threaded steel rod or bolts, punched in the top of the channel at regular 48 mm (1 7/8 inch) centers. Half-slot channel has short, rounded end rectangular slots punched out on 50 mm (2 inch) centers. Slot channel has longer slots on 100 mm (4 inch) centers. In metric system based products, the eyelets are about 11×13 mm.
