Fastener Kits for Enclosures

Mount components to your enclosure without worrying about leaks—these kits seal out water from washdowns, rain, and snow when used with enclosures rated NEMA 4X. They’re made of stainless steel, so they won’t corrode in outdoor or corrosive environments.

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).
