Electricians and DIYers, stock up on these handy cable connectors! This pack includes 30 gray, non-metallic push-in connectors in 3/8-inch trade size (fits 1/2-inch knockouts). Made from tough nylon plastic, they're designed for quick and secure installation – just push the connector into the knockout hole in your junction box, then insert the cable. They grip firmly to prevent cables from pulling loose. Perfect for connecting non-metallic sheathed (NM) cables to metal boxes or housings in residential wiring. No tools needed for installation, but you can use a flat-head screwdriver to release them if needed. A reliable, affordable solution for keeping your electrical projects neat and safe. Great for large jobs or keeping extras in your toolkit!
