Trending Abb 52cadj1612 Single Gang Adjustable Mud Ring

The ABB 52cadj1612 is a single-gang adjustable mud ring designed for use with 4-inch square electrical boxes. It adjusts from 3/4 inches to 1-1/2 inches in depth, making it suitable for installations where drywall or wall-finish thickness is not uniform. Constructed from pre-galvanized steel, the ring provides corrosion resistance in typical wall and ceiling rough-in environments. Electricians use this type of mud ring to set device boxes flush with the finished wall surface before cover plates and devices are installed.

This mud ring is intended for residential and light commercial electrical rough-in work where 4-inch square back boxes are installed in drywall assemblies. The adjustable depth range accommodates variation in drywall thickness across a single job site or between floors, reducing the need to stock multiple fixed-depth rings. Adjustment screws remain accessible even after the device is seated, allowing fine-tuning once drywall is hung and finished.

Key Features

• Depth adjusts from 3/4 inches to 1-1/2 inches to match variable drywall thickness
• Pre-galvanized steel construction for durability in wall and ceiling assemblies
• Single-gang configuration accommodates one outlet, switch, or device
• Adjustment screws remain accessible after device installation for easy fine-tuning
• Designed for use with standard 4-inch square electrical boxes

Compatibility

Designed for use with 4-inch square electrical back boxes in single-gang device installations. Suitable for drywall assemblies where finished wall depth varies.

Installation Notes

Installation is typically performed by a licensed electrician during the rough-in or finish stage of electrical work. Power to the circuit must be off and verified before any work is performed inside the box. Mud rings should be set to the appropriate depth before drywall finishing is complete, but the accessible adjustment screws allow correction after drywall is in place. Follow applicable NEC requirements for device box fill and flush-mount installations.
