Clamp-On Framing and Fittings

Fittings come in two pieces to wrap around rails, so you can quickly modify existing structures without disassembling. Use clamp-on framing and fittings to form temporary partitions, modular conveyors, and workstations. 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; drill a matching hole in the rail and secure with a fastener (not included).
