RACO 868AMR 4-11/16 in. Adjustable Mud Ring Cover, Single Device, Square

RACO 868AMR 4-11/16 in. Adjustable Mud Ring Cover, Single Device, Square

The RACO 868AMR is a 4-11/16 in. square adjustable mud ring engineered to mount a single device—such as a toggle switch, receptacle, or dimmer—flush with the finished wall surface when paired with a 4-11/16 in. square electrical box. Because the ring's depth is adjustable, installers can fine-tune the device opening to match varying wall thicknesses, from thin drywall to thicker plaster or tile assemblies, without swapping parts. The square profile of the 868AMR is purpose-built to align precisely with standard 4-11/16 in. square box openings, and the cover carries a UL Listing for use on code-compliant commercial and residential wiring projects.

Key Features

• 4-11/16 in. Square Box Fit: Sized specifically for 4-11/16 in. square electrical boxes, the 868AMR mud ring seats securely over the box opening for a clean, professional appearance.
• Adjustable Depth Design: The adjustable mud ring lets electricians set the device mounting depth on the jobsite, compensating for different wall material thicknesses so the finished device sits flush with the surrounding surface.
• Single Device Opening: Configured for a single device—switch, receptacle, or similar—the 868AMR keeps the installation compact and simplifies device trim-out.
• Square Shape: The square geometry matches standard square box footprints, reducing gaps and providing a snug, secure fit against the box.
• Raised Cover / Mud Ring Function: As a raised device cover, the 868AMR bridges the distance between the recessed electrical box and the finished wall, a critical step when boxes are installed before wall material is applied.
• UL Listed Construction: Independently UL Listed, the 868AMR meets recognized safety standards for use in commercial and residential electrical systems.
