Knockout bushing pack
This 50-piece pack of 1-1/4-inch nylon knockout bushings protects cable insulation where wires pass through metal knockouts in electrical boxes or panels. Electricians and maintenance crews use them to meet code requirements for abrasion protection on commercial and residential job sites. The nylon material resists cracking during installation and remains stable across normal temperature ranges. Each bushing snaps into place without tools for fast rough-in work.
Sustained job-site performance
Nylon construction withstands repeated cable pulls and vibration without deforming or splitting, keeping the protective edge intact over the life of the installation. The material does not conduct electricity, so it maintains isolation between the cable sheath and the metal enclosure under continuous load. UV resistance allows use in exposed locations where sunlight degrades lesser plastics. Bulk packaging reduces reorder frequency on long projects.
Decisive specification
The 1-1/4-inch trade size fits standard concentric knockouts in metallic boxes and conduit bodies, making it the single dimension that determines compatibility with the enclosure. Installers must verify the knockout diameter matches this trade size before purchase. The 50-count quantity suits crews that run multiple circuits per job but may exceed the needs of a single-service upgrade. Buyers who need a different trade size or a smaller pack quantity should select another listing.

Questions about this item
Does the DOTTIE 1213D knockout bushing generate any noise or heat when installed in conduit that runs continuously?
The nylon knockout bushing is a passive component with no moving parts or electrical draw, so it produces no noise or heat during continuous operation.
What tools or materials must I already have to install the 1-1/4 inch DOTTIE 1213D bushings?
You will need a standard 1-1/4 inch knockout punch or hole saw, plus the electrical box or panel you are mounting the bushings into.
Will the DOTTIE 1213D bushing fit the existing 1-1/4 inch knockouts on my older metal junction boxes?
Yes, the bushing is sized for standard 1-1/4 inch trade-size knockouts found on both new and older metal boxes.
