Adjustable mud ring

Thomas & Betts

The Steel City adjustable mud ring ensures that stud-mounted outlet boxes fit flush with any thickness of finished drywall, plaster, or ceramic tile, according to the company. Features include an inner ring that adjusts from ½ in. to 1½ in. to accommodate various drywall thicknesses. Two adjustment screws enable the inner ring to be set at the anticipated depth prior to installation and adjusted after installation. Mountable to 4-in.-square metallic deep outlet boxes, the device offers the rugged steel construction of a standard mud ring with enhanced flexibility.
