Orbit Industries MSBG-1 Gangable Masonry Switch Box

Product Description

The ORBIT INDUSTRIES MSBG-1 is a single-gang gangable masonry switch box built for residential and commercial electrical rough-in work. Constructed from 16-gauge galvanized sheet steel, it provides a durable, corrosion-resistant enclosure for wiring devices in masonry wall installations. The box measures 1-7/8 inches wide by 3-3/4 inches tall by 2-1/2 inches deep, giving electricians the interior volume needed for standard switches and receptacles. Knockout openings are provided on the sides (4 CKO) and bottom (1 CKO), allowing flexible conduit entry from multiple directions. The gangable design lets installers join multiple boxes side by side when additional device space is required.

The MSBG-1 is intended for masonry wall applications in both residential and light commercial construction. It is commonly installed during rough-in phases where devices will be set into block, brick, or concrete walls. Electricians use it with conduit systems where rigid or flexible metal conduit is routed through the knockout openings. The gangable feature makes it well suited for multi-device locations such as panel switches, multi-outlet banks, or data and low-voltage co-located assemblies.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes.
