Arlington Industries 8400ST SNAP-TITE® 3/8" Combination FMC/AC Connector

Arlington Industries 8400ST SNAP-TITE® 3/8" Combination FMC/AC Connector

Arlington Industries engineered this SNAP-TITE® 3/8" Combination Connector to give electricians a single, dependable fitting for joining both flexible metal conduit (FMC) and armored cable (AC/BX) to boxes, panels, and enclosures. Rather than stocking separate connectors for FMC and BX runs, contractors can rely on this 3/8" combination-style connector to handle either cable type through the same knockout. The SNAP-TITE® mechanism snaps the connector securely into place without set screws, cutting down on installation steps and speeding up rough-in work on residential and commercial jobs alike. Built by Arlington Industries for professional electrical installations, this connector helps keep panels, junction boxes, and enclosures organized and code-ready.
