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).

Through-hole fittings allow rails to run all the way through.
Hinges provide smooth motion at the junction between two rails.
