Arlington CP3540 Box Cover, White, Non-metallic, Paintable, for Unused 3-1/2" or 4" Electrical/Pan Boxes

Keep ceilings neat and code-conscious while simplifying security and surveillance installs with the Arlington CP3540 ceiling box cover. Designed for unused 3-1/2 in or 4 in electrical/pan boxes, this white, paintable non-metallic mounting plate hides open openings and creates a professional finished look for monitoring, networking, and low-voltage systems. The deeper cover profile works with pan boxes without the need to cut the post, reducing labor time during retrofits and new construction. Installers benefit from two separate mounting options: a push-in threaded post for smooth, flat ceilings and a screw-on option for textured or uneven surfaces, ensuring a secure fit in any environment. Made of durable plastic and manufactured in the US, the CP3540 resists rust and corrosion—ideal for long-term use in security camera, access control, and building monitoring deployments. Use it wherever a discreet, paintable ceiling cover is needed to conceal unused electrical boxes and maintain a finished appearance.
