Heavy Duty Clamp-On Framing and Fittings
Build workstations, conveyors, and shelving for heavy loads. These clamp-on framing rails and fittings are the thickest and sturdiest in our offering. The fittings slide over the rails in one piece. Tighten their bolts to clamp them in place—no machining or welding required.
Through-hole fittings allow rails to run all the way through.
Aluminum fittings resist corrosion in wet environments. 304 stainless steel fittings resist corrosion better than aluminum and plastic fittings. They also resist mild chemicals such as cleaners. Plastic fittings are nonconductive and lightweight. They also have good chemical resistance.

Clamp-On Framing and Fittings
Fittings come in two pieces to clasp over rails, making assembly and disassembly quicker than our other framing. Use it to form temporary partitions, modular conveyors, and workstations. To assemble, clamp fittings onto the rail and tighten the included cap screw and nut. For permanent connections and added strength, fittings have a 5/32" hole to drill in an additional screw (not included).
Galvanized Iron and Steel Slip-On Framing and Fittings
To provide corrosion resistance in wet environments, this framing is galvanized. Slip the fittings over rails to construct custom railings, guard rails, storage racks, and shelving. Tighten the included set screws for a secure hold.
Galvanized iron fittings are malleable iron.
Through-hole fittings allow rails to run all the way through.

Scaffold Clamps
Build tube-and-clamp scaffolding and attach supports, such as railings, to frame-style structures. Also known as knuckles. These clamps fit the most common scaffold tube sizes. Made of galvanized steel, they are rust resistant and hold up in outdoor applications.
Rigid clamps create a secure 90° connection between two tubes.
Swivel clamps pivot to connect tubes at any angle.
Note: Clamps meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
