Knock-out Wire Bushings

Protect your cables from sharp metal edges with Dicio’s durable snap-in knock-out bushings. These push-in hole bushings fit standard electrical box knockouts and provide a secure, tool-free installation—ideal for electricians, contractors, and DIY users handling metal junction boxes or panel enclosures.

Our bushings are made from tough, heat-resistant nylon to prevent abrasion, reduce strain on wires, and ensure safer cable routing. Whether you're sealing unused knockouts or adding strain relief to romex/non-metallic cables, Dicio bushings help keep every installation clean, compliant, and long-lasting.
