Southwire/coleman Cable MSB3G 3 Gang Smart Box

Product Description

The SOUTHWIRE/COLEMAN CABLE MSB3G is a 3-gang smart box designed for mounting electrical devices in new construction and retrofit wall applications. Built from extra-thick PVC, the box delivers the structural rigidity required to support multiple devices in a single gang location. Heavy-duty mounting screws are included, and all device holes are pre-threaded for faster installation. At 4.7 pounds, the MSB3G is a solid, robust enclosure suited for licensed electricians working on residential and light commercial projects. It accepts mounting to both wood and metal studs, making it flexible across framing types.

The MSB3G is appropriate for standard single-location 3-gang wall installations where smart devices, switches, receptacles, or combination devices need to be grouped. Its compatibility with both wood and metal stud framing makes it a practical choice for electricians in residential new construction, remodel work, and light commercial build-outs. The pre-threaded device holes reduce the time spent fitting screws and setting devices during rough-in and trim-out phases. Package quantity is 8 units per case.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits at the breaker panel before making any wiring connections. Confirm stud spacing and box depth meet local code requirements for the device types being installed. Secure the box firmly to the stud before pulling wire to prevent movement during device trim-out.
