Arlington BE4X Four Gang XL Box Extension

Gain dependable device support in miscut or oversized openings with the Arlington BE4X Four Gang XL Box Extension. This Arlington Industries box extender levels and stabilizes wiring devices—switches, outlets and low-voltage terminations—so security, surveillance and monitoring equipment mounts flush and operates reliably. The four-gang design extends an existing back box up to 1-1/2 in., giving the extra reach needed when the box is set back from the finished surface. Larger perforated flanges create stronger fastening points, speeding installation and reducing drywall repair and callbacks. Constructed of durable white plastic and sized at 7.75" x 4.63", the BE4X installs quickly and maintains neat, code-compliant terminations. A 2-hour fire rating provides added protection where fire performance is required in commercial, institutional and critical infrastructure projects. Ideal for electricians, low-voltage integrators and security installers, this box extension improves mounting stability for cameras, access control, networking outlets and other monitoring hardware. Add the Arlington BE4X to your standard job kit to streamline installs and protect your surveillance and security investments—order now to standardize your next project.
