Helpful Buying Guide

Choose box accessories for the opening, enclosure, or equipment task

Start by identifying what needs to be adapted, covered, serviced, or added. The products represented here differ by function: reducing bushings change a threaded conduit opening to a smaller size, knockout seals cover unused openings, hinge pins support enclosure-door servicing, and the caster and fan kits address specified equipment setup needs.

Use Cases

Match the accessory to the task

Use reducing bushings when a threaded opening must accept smaller rigid or IMC conduit. Choose knockout seals to cover unused knockout openings in metal enclosures or outlet boxes. Select hinge pins for removing, replacing, or reversing an enclosure door.

How to Choose

Confirm the key dimensions and configuration

For bushings, compare both the threaded opening size and the conduit size to be accepted. For seals, match the listed knockout size and choose snap-in or three-piece construction. For kits, verify the stated caster diameter or the fan’s 4-inch size, 115 VAC operation, and overall dimensions.

Applications

Support installation and maintenance work

These components are used by electricians, electrical contractors, maintenance professionals, panel-building teams, and equipment buyers. Typical tasks include conduit transitions, closing exposed openings, working around existing wires, enclosure-door service, and fixed-position equipment configurations.

Planning Guide

Plan the right fit before choosing

Conduit opening reduction

Select reducing bushings by the exact size transition

Reducing bushings adapt larger threaded openings for smaller conduit in rigid or IMC installations. Compare the opening size first, then the conduit size the bushing is intended to accept.

  • 1-1/4 in. opening to 1 in. conduit
  • 1-1/2 in. opening to 1 in., 1-1/4 in., or 3/4 in. conduit
  • Zinc alloy construction
  • 25-piece pack quantities
Unused knockout coverage

Choose seals based on opening size and installation approach

Knockout seals cover exposed, unused openings in compatible metal enclosures and outlet boxes. A 2-inch snap-in option provides a direct installation approach, while the three-piece styles use a screw and strap and can be installed from inside or outside the box without rearranging existing wires.

  • Snap-in carbon steel seals for 2-inch openings
  • Three-piece carbon steel seals in 2-1/2, 3-1/2, 4-1/2, and 5 inch sizes
  • Screw-and-strap retention on three-piece styles
  • 10-pack quantities for three-piece seals
Enclosure and equipment components

Check the stated setup requirements before selecting a kit

For enclosure-door service, the hinge pin kit provides removable pins that support door removal, replacement, or reversal. For equipment setups, compare the stationary caster kit’s 3-inch diameter with the fan kit’s 4-inch size, 115 VAC operation, and 6.25 x 8.75 x 6.25 inch overall dimensions.

  • Two Type 304 stainless steel hinge pins per kit
  • Two stationary casters with a 3-inch diameter
  • 4-inch fan kit for 115 VAC operation
  • Fan kit combines steel and plastic components
