Orbit MBG-1 Gangable 1-Gang Masonry Box, 3-1/2" Deep

Orbit MBG-1 Gangable 1-Gang Masonry Box, 3-1/2" Deep

The Orbit MBG-1 is a 3-1/2" deep, gangable 1-gang masonry box with a concentric knockout (CKO), built from 16 gauge sheet steel for use in concrete block, brick, and other masonry wall construction. Sized at 1-7/8-Inch x 3-3/4-Inch x 3-3/4-Inch, this rugged steel box is engineered to be set directly into masonry walls during construction, providing a durable, code-ready enclosure for switches, receptacles, and other wiring devices in commercial and institutional buildings. The gangable design allows multiple MBG-1 boxes to be joined together on the jobsite to create multi-device masonry boxes without needing to stock separate multi-gang parts, saving time and reducing inventory complexity for electrical contractors working on masonry construction projects.
