Abb 52cadj2 Adjustable Mud Ring 4 in Two Gang Steel

Product Description

The ABB INSTALLATION PRODUCTS 52cadj2 is a two-gang adjustable mud ring designed for use with 4-inch square electrical boxes. Built from pre-galvanized steel, it adjusts from 1/2 inch to 1-1/2 inch of raised depth, allowing a single device to accommodate varying drywall thicknesses without requiring multiple fixed-depth rings on hand. The patent-pending design delivers the same rugged construction electricians expect from a standard mud ring while adding the flexibility needed in situations where wall depth is inconsistent. Licensed electricians use this ring during rough-in and finish-out phases on commercial and institutional electrical installations.

This adjustable mud ring is well suited for hospital construction and similar institutional projects where drywall depth often varies between rooms or floors. Its compatibility with standard 4-inch square boxes makes it a practical stock item for electrical contractors working on multi-room or multi-floor projects. The silver pre-galvanized steel finish provides corrosion resistance appropriate for interior wall assemblies. The adjustable design reduces the need to carry multiple fixed-depth mud rings on the job site, simplifying material staging and reducing waste.

Installation Notes

Installation of this mud ring is typically performed by a licensed electrician during the rough-in or finish-out stage of construction. De-energize the circuit and confirm power is off at the breaker before working inside any electrical box. Adjust the ring depth to match the finished wall surface before securing to the box, and verify alignment is flush with the drywall face prior to device installation. Work must comply with applicable sections of the National Electrical Code (NEC) and any local amendments.
