1" Nylon Knockout Bushing 100PK

This pack supplies one hundred 1-inch nylon knockout bushings for electrical and mechanical installations. Contractors and maintenance teams use them to protect cables passing through punched metal openings. The nylon material resists abrasion and chemical exposure in conduit systems. Each bushing snaps into standard knockout holes without tools.

100-piece bulk capacity

The 100-count package covers multiple junction boxes, panels or equipment enclosures on a single job. It handles routine cable-protection needs across commercial and residential sites. The quantity runs out when a project demands larger-diameter bushings or non-standard knockout sizes. Reordering is simple when the box is empty.

Fits 1-inch knockouts in metal boxes

These bushings install directly into 1-inch diameter knockout holes in steel or aluminium enclosures. No adhesives, screws or special tooling are required for a secure fit. The smooth nylon bore frees cables from sharp metal edges that can damage insulation over time. They work with THHN, NM-B and other common wire types.

Questions about this item

Will the 1" knockout bushing fit the existing 1" knockouts in my older metal junction boxes?

The 1" nominal size matches standard 1" knockout openings, so the bushing seats in the same cut-outs used by older boxes.

How can I confirm each nylon bushing is seated correctly after installation?

Press the bushing until its flange sits flush against the box wall; the tapered skirt should snap into the knockout and resist pull-out by hand.

Does the 100-pack include mounting screws or locknuts, or must I supply them separately?

The pack contains 100 nylon bushings only; screws, locknuts or other fasteners are not included and must be purchased separately.
