Orbit Industries MB-4 Steel Switch Box 4 Gang 3.5 Inches Deep

Product Description

The ORBIT INDUSTRIES MB-4 is a 4-gang steel switch box designed for residential and commercial electrical wiring installations. Constructed from 16-gauge galvanized sheet steel, this box measures 7.375 inches wide by 3.75 inches tall by 3.5 inches deep, providing ample interior volume for device mounting and wire management. The galvanized finish resists corrosion in standard interior environments. Four concentric knockouts (CKO) on the sides and four CKO knockouts on the bottom allow flexible conduit entry from multiple directions, simplifying rough-in work in new construction and retrofit applications. Licensed electricians rely on this box for multi-device switch and receptacle installations where a durable, code-compatible enclosure is required.

The MB-4 suits multi-gang device installations in both residential and light commercial settings. Its 3.5-inch depth accommodates standard wiring methods including conduit runs entering from the side or bottom knockouts. The box is appropriate for use in wood-frame wall assemblies and similar installations where a steel enclosure is specified. It supports the mounting of up to four devices side by side, making it a common choice for hallway switch banks, panel-adjacent device clusters, and commercial switch stations.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the circuit at the breaker panel and verify zero voltage with a meter before beginning work. Use appropriate knockout punches or a screwdriver and hammer to remove only the CKO entries needed for the conduit run. Secure the box firmly to framing members before pulling wire to prevent movement during device installation.
