Half-Inch Knockout Bushing

DOTTIE 1210D nylon bushings protect cable insulation when pulling wires through half-inch knockout holes in electrical boxes and panels. The 100-piece pack supplies enough fittings for multiple residential or light-commercial rough-in jobs. Electricians and maintenance technicians use them to prevent sharp metal edges from damaging conductors during installation.

Capacity and Headroom

One hundred bushings cover large projects or several smaller service calls without reordering. The nylon material resists cracking when snapped into standard half-inch knockouts and withstands typical job-site temperatures. The pack runs out when the project demands more than one hundred openings or when a different knockout size is required.

Half-Inch Trade Size

These bushings fit only half-inch knockout openings; they will not seat in three-quarter-inch or larger holes. Buyers needing assorted sizes or metallic bushings for code-specific applications must source those separately.

Questions about this item

Will the 1/2'' nylon knockout bushings fit the existing 1/2'' knockouts in my older electrical boxes?

Yes, each bushing is sized for a standard 1/2'' knockout, so they match the openings already cut in your existing boxes and panels.

How can I confirm the bushings are seated correctly after installation?

After snapping a bushing into the knockout, the flange should sit flush against the box wall and the inner throat should be smooth with no sharp edges visible.

Does the 100-pack include any installation tools or locknuts, or must I buy those separately?

The package contains only the 100 nylon knockout bushings; locknuts and any tools are not included and must be purchased separately.
