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).




Flanged rails have a flat edge for storing bin boxes on top. For bin boxes that have a lip, you can turn the flange to the side and hang the bin boxes.
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.

An anodized finish resists corrosion and wear better than plain aluminum.

Light Duty Aluminum Telescoping Framing and Fittings
Create lightweight adjustable structures. With telescoping aluminum rails, this framing is often used to make folding stands, extension poles, and sign frames. To telescope rails, slide one length of rail into the next larger size and connect using the corresponding locks.

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.
