The ABB Installation Products SCA410 is a 1-gang mud ring designed for use with 4-inch square electrical boxes. It provides a 1/2-inch raised profile, allowing for the proper depth adjustment needed when finishing walls with drywall or plaster. Electricians use mud rings to bring the device mounting surface flush with the finished wall surface. This fitting is sold individually and is a standard component in commercial and residential rough-in wiring work where square electrical boxes are specified.
This mud ring is suited for new construction and retrofit installations where 4-inch square outlet boxes are installed in walls or ceilings. The 1/2-inch raised height accommodates typical single-layer drywall applications. It mounts directly to the face of a 4-inch square box and accepts standard single-gang wiring devices such as switches, receptacles, and low-voltage plates.
Designed as an OEM-style replacement and standard fitment accessory for 4-inch square electrical boxes requiring a 1-gang, 1/2-inch raised mud ring.
Installation is performed by licensed electricians during rough-in or finish stages of construction. De-energize the circuit and verify power is off before handling any box hardware or wiring devices. Secure the mud ring to the face of the square box before wall finishing to allow the raised collar to sit flush once drywall or plaster is applied. Work should comply with applicable NEC requirements for device box fill and mounting.
