Orbit MSBG-1 Gangable 1-Gang Masonry Box, 2-1/2" Deep with CKO

The Orbit MSBG-1 is a 1-gang masonry box built 2-1/2" deep to provide ample interior volume for device and conductor installations in masonry, block, and brick wall construction. This box is gangable, allowing multiple units to be joined together on the job site to create multi-gang configurations from a single-gang component, giving electricians flexibility when box layout requirements change in the field. The MSBG-1 comes equipped with a CKO (concentric knockout) for streamlined conduit entry, reducing the need for field drilling and simplifying rough-in work on concrete and masonry projects.

Key Features

  • Box Depth: 2-1/2" deep design provides generous interior space for wiring devices, splices, and conductor fill in masonry wall applications.
  • Gangable Design: This box can be ganged together with additional units to form multi-gang assemblies, offering on-site flexibility for electricians configuring device layouts.
  • 1-Gang Configuration: Sized to accommodate a single device or wiring configuration, ideal for standard masonry rough-in applications.
  • CKO Knockout: Equipped with a concentric knockout (CKO) for efficient, pre-sized conduit entry points, reducing on-site fabrication time.
  • Masonry-Rated Construction: Purpose-built for installation in concrete block, brick, and other masonry wall systems commonly found in commercial and institutional construction.

Orbit MSBG-1 – Frequently Asked Questions

1) Will the Orbit MSBG-1 masonry box work in concrete block wall rough-in?
That is what the MSBG-1 is built for. It is a masonry box intended for installation in concrete block, brick, and other masonry wall systems during rough-in, with a 2-1/2 inch deep body that sets into the block cell. Standard use is commercial and institutional masonry construction, both new work and renovation.
2) Can I gang Orbit MSBG-1 masonry boxes together for a 2-gang or 3-gang device layout?
Yes. The MSBG-1 is a gangable 1-gang box, so units join together on site to build 2-gang, 3-gang or larger assemblies. That means you stock one part number and set the gang count at the wall instead of carrying separate multi-gang boxes. Order one MSBG-1 per gang you need.
3) Does the Orbit MSBG-1 masonry box come with a knockout for conduit, or do I have to drill it?
It ships with a CKO, a concentric knockout, so conduit entry is pre-sized and you are not field drilling the box during rough-in. Concentric means you knock out the ring that matches your conduit size rather than being locked to one trade size.
4) Is a 2-1/2 inch deep masonry box enough volume for a receptacle plus pass-through conductors?
The 2-1/2 inch depth is the deeper of the common masonry box choices and is specified where you need room for a wiring device plus splices and conductors feeding through. Shallower masonry boxes get tight once you have a device and more than one conduit entry. Conductor fill still has to be calculated against the box's cubic-inch rating for your conductor count.
5) Can I use the MSBG-1 in a stud wall with drywall instead of masonry?
It is the wrong box for that. The MSBG-1 is a masonry box, sized and configured to be grouted into block, brick, or concrete construction. For wood or steel stud framing behind drywall, use a standard new-work device box with bracket or nail-on mounting instead.
6) What is the Orbit part number for a 1-gang masonry box 2-1/2 inches deep?
Orbit MSBG-1. It is the single-gang, gangable masonry box in the 2-1/2 inch depth, supplied with a concentric knockout.
