Diversitech 750-rc841 Romex Connector 3/8 in 1/2 in Knockout

Product Description

The DIVERSITECH 750-rc841 is a metallic Romex connector designed to secure Romex (NM-B) cable through 1/2 inch knockout openings in electrical enclosures, panels, and junction boxes. Built from zinc die cast, this connector provides a solid, low-profile termination point for non-metallic sheathed cable. Electricians use this connector to maintain a clean, code-compliant cable entry where NM-B cable transitions into a metal box or panel. The 3/8 inch connector body seats into standard 1/2 inch knockouts for a secure mechanical fit.

This connector is suited for residential and light commercial electrical installations where Romex cable is routed into metal enclosures. Common applications include service panels, sub-panels, junction boxes, and disconnect enclosures. It is installed by licensed electricians and experienced electrical contractors during rough-in or service work. The connector is sold individually.
