Railing Clamps
Clamp onto metal tubes such as pipe, scaffolding, and railing to hang lighting fixtures, threaded rod, and equipment. Made of aluminum, all of these clamps are lightweight and have good corrosion resistance.
Clamps with a black anodized finish blend into dark backgrounds and are more corrosion resistant than unfinished clamps.
Style A clamps have grooves on the inside to improve grip. To mount equipment, remove the bolt on the bottom of the hanger, mount the equipment, and reattach the bolt. To hang threaded rod, remove the bolt and replace it with threaded rod.
Style B clamps have a T-handle for attachment and removal. To mount equipment, remove the bolt on the bottom of the hanger, mount the equipment, and reattach the bolt. To hang threaded rod, remove the bolt and replace it with threaded rod.
Style C clamps have wing nuts for making adjustments. Remove the wing nut from the bottom bolt and reattach after mounting equipment.
Style D clamps have a wing nut and a bolt for making adjustments. To mount equipment, remove the bolt on the bottom of the hanger, mount the equipment, and reattach the bolt. To hang threaded rod, remove the bolt and replace it with threaded rod.

Heavy Duty Clamp-On Framing and Fittings
Thick construction makes this framing strong and sturdy. This system has a secure clamping mechanism to hold heavy loads—no machining or welding required. Use clamp-on framing and fittings to form temporary partitions, modular conveyors, and workstations. Clamp fittings onto the rail and tighten the included hex head screws.

Through-hole fittings allow rails to run all the way through.
Adjustable-angle fittings can be positioned at any angle. Tighten the hex head screw to secure.

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.
Add-on through-hole fittings have a hinge, so you can fit them onto existing rails without disassembling. A quick-release lever makes removal easy.
