Orbit GB-1-MC-OW 1-Gang Gangable Switch Box with MC Clamps, Galvanized Steel

The Orbit GB-1-MC-OW is a 2-1/2" deep, gangable 1-gang switch box built from 16 gauge galvanized sheet steel, engineered specifically for old work (remodel) installations. Measuring 2-Inch x 3-Inch x 2-1/2-Inch, this device box features integrated BX/MC cable clamps and locking grips that allow it to be securely mounted in existing finished walls without the need for additional framing access. The gangable design lets installers combine multiple boxes side by side to create multi-device configurations on the job site, while the rugged galvanized steel construction stands up to the demands of daily commercial and residential electrical rough-in work.

Key Features

  • Trade Size: 2-1/2" deep box measuring 2-Inch x 3-Inch x 2-1/2-Inch, sized for standard single-device switch and receptacle installations.
  • Durable Construction: Fabricated from 16 gauge galvanized sheet steel for corrosion resistance and long-term structural integrity in demanding electrical applications.
  • Gangable Design: Box sides are designed to gang together, allowing electricians to build 2-gang, 3-gang, or larger multi-device assemblies as required by the job.
  • Integrated MC/BX Cable Clamps: Built-in cable clamps secure BX and MC armored cable directly at the box, eliminating the need for separate connectors and speeding up rough-in time.
  • Locking Grips for Old Work: Integrated locking grip tabs clamp the box firmly to existing drywall or plaster, making this box purpose-built for remodel and retrofit installations where new framing is not accessible.
  • 1-Gang Configuration: Sized to accept a single switch, receptacle, or wiring device for standard residential and light commercial circuits.
  • Galvanized Finish: Zinc-galvanized steel surface helps resist rust and corrosion throughout the life of the installation.

Orbit GB-1-MC-OW – Frequently Asked Questions

1) Can the Orbit GB-1-MC-OW switch box be installed in an existing finished wall without opening the drywall?
That is what it's built for. The GB-1-MC-OW has integrated locking grip tabs that clamp the box to existing drywall or plaster, so you can add a device in a finished wall without getting at the framing. The box measures 2 x 3 x 2-1/2 inches, so you cut the opening to the box and the grips hold it from behind.
2) Does the Orbit GB-1-MC-OW need separate MC cable connectors?
No. BX/MC cable clamps are built into the box, so armored cable lands directly at the box without buying separate connectors. If you are pulling NM romex instead, this is the wrong clamp type for that cable.
3) Should I use a nonmetallic box instead of the Orbit GB-1-MC-OW for a remodel device add?
It depends on the wiring method and the box count. The Orbit GB-1-MC-OW is galvanized steel with integrated MC/BX cable clamps, so it is the choice when you are pulling armored cable and want the cable secured at the box. If you are running nonmetallic cable and do not need a metal enclosure, the Allied Moulded FlexBox Series thermoplastic switch box or the Allied Moulded 4304-NK fiberglass reinforced thermoset polyester box are the nonmetallic options. Note that the 4304-NK is a 4-gang box, so it is not a swap for a single-device opening.
4) What is the closest steel alternative to the Orbit GB-1-MC-OW 1-gang gangable switch box?
The Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is the nearest peer: it is also a 1-gang gangable switch box, built in pre-galvanized steel. The Orbit GB-1-MC-OW is galvanized steel as well and is a 2-1/2 inch deep 1-gang gangable box with integrated MC/BX cable clamps and locking grips for old work. If your rough-in uses BX or MC armored cable and you want the clamps built into the box, the Orbit unit covers that at the box; the Steel City Adjust-A-Box is the alternative when you want an adjustable-depth gangable steel box.
5) Can I gang two or three Orbit GB-1-MC-OW boxes together for a multi-switch opening?
Yes. The sides come off so boxes join side by side, letting you build 2-gang, 3-gang or larger device assemblies on site from single 1-gang boxes.
6) How deep is the Orbit GB-1-MC-OW, and will it fit a 2x4 stud wall?
Box depth is 2-1/2 inches, with overall dimensions of 2 x 3 x 2-1/2 inches. That clears inside a nominal 2x4 wall (3-1/2 inch actual stud depth) with room behind the box.
7) What else could I use instead of the Orbit GB-1-MC-OW for a 1-gang old work steel box?
The closest cross-brand equivalent we carry is the Thomas & Betts LXWOWC-25, a Steel City Adjust-A-Box 1-gang gangable old work switch box in pre-galvanized steel. Same category of install, same gangable single-device format, in Steel City's Adjust-A-Box series rather than Orbit.
8) I need four devices in one opening. Is the Orbit GB-1-MC-OW still the right box?
You can get there two ways. The Orbit GB-1-MC-OW is gangable, so multiple 1-gang boxes gang side by side to build a 2-gang, 3-gang or larger assembly on the job, and each section keeps its own MC/BX clamps. If you would rather set a single one-piece enclosure, the Allied Moulded 4304-NK is a 4-gang box in fiberglass reinforced thermoset polyester. The Orbit route stays metallic and clamps armored cable at the box; the 4304-NK is a nonmetallic single unit.
9) What is the Orbit part number for the 1-gang old work box with MC clamps?
Order it as Orbit GB-1-MC-OW. The suffixes tell you the configuration: MC for the integrated MC/BX cable clamps, OW for old work mounting with locking grips.
