Arlington 8410 MC Connector, 3-1/2"

Keep MC cable terminations fast, secure, and protected with the Arlington Industries 8410 MC connector — a purpose-built conduit adapter for low-voltage and security systems. Designed to attach MC cable to a 3-1/2" knockout, this connector provides a durable, code-friendly termination that reduces cable strain and preserves signal integrity for surveillance, monitoring, and network deployments. Constructed from zinc die-cast metal, the 8410 resists corrosion and wear for dependable service life in commercial CCTV, access control, and IT infrastructure projects. The integrated round end stop (2.830" diameter) protects cable jackets from sharp knockout edges, minimizing rework and cable damage. Installation is simple and secure: the connector fastens to the knockout with a locknut for a tight, tamper-resistant fit and UL-listed performance. Supplied in packs of five and manufactured in the U.S., this Arlington Industries MC connector helps contractors and integrators streamline conduit terminations on security and networking jobs.
