Arlington 8418 Connector for Larger MC Cable, 3-1/2"

For fast, dependable termination of larger MC feeders, the Arlington Industries 8418 connector provides a rugged, job-site-ready solution. This conduit adapter secures steel or aluminum MC cable into a 3-1/2" knockout using a heavy-duty zinc die-cast body and steel strap, offering long service life and corrosion resistance where reliability matters. Built-in end stop and additional bushings accommodate a wider range of cable diameters, reducing the need for multiple connector SKUs and speeding installation for electrical contractors and low-voltage integrators. The connector installs with a steel locknut and becomes concrete-tight when taped, safeguarding cable ends during pours — an important benefit for infrastructure, surveillance, security, and building monitoring projects. Ideal for commercial and industrial cabling, the Arlington 8418 helps ensure code-compliant connections for power and control runs that support networking, security cameras, and access control systems. Specify this MC connector to minimize labor, protect terminations, and keep projects on schedule. Order the Arlington 8418 connector for your next conduit or concrete application and simplify larger MC cable terminations.
