Orbit Industries MBG-1 Gangable Masonry Switch Box

Product Description

The ORBIT INDUSTRIES MBG-1 is a single-gang gangable masonry switch box designed for device mounting in concrete block and masonry wall installations. Constructed from 16-gauge sheet steel with a galvanized finish, this box measures 1.875 inches wide by 3.75 inches tall by 3.5 inches deep. It features combination knockouts on all four sides and one combination knockout on the bottom, providing flexible conduit entry for multiple wiring configurations. Licensed electricians install this box during rough-in on masonry construction projects where a standard device box is required.

The MBG-1 is suited for both residential and commercial wiring installations where devices such as switches or receptacles are mounted in masonry or concrete block walls. Its gangable design allows adjacent boxes to be joined side by side to accommodate multi-device configurations without additional hardware. The galvanized steel construction holds up in the demanding conditions common to masonry rough-in work.

Key Features

• Gangable construction allows multiple boxes to be joined for multi-device installations
• 16-gauge sheet steel body provides rigid, durable device support
• Galvanized finish resists corrosion in masonry environments
• Four side combination knockouts (CKO) for flexible conduit routing
• One bottom combination knockout (CKO) for additional conduit entry
• 3.5-inch depth accommodates wiring and device connections in masonry walls

Compatibility

Designed as an OEM-style replacement and standard fit for single-gang masonry wall installations in residential and commercial electrical wiring applications.

Installation Notes

Installation of this masonry box should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize all circuits in the work area before beginning installation or wiring connections. Secure the box in the masonry opening before pulling conductors, and verify that all knockouts are properly removed and bushings or fittings are installed as required by code. Do not overtighten device screws in the threaded ears, as this can distort the box and affect device alignment.
