Orbit GB-1-MC 2-1/2" Deep Gangable 1-Gang Switch Box with MC Clamps

The Orbit GB-1-MC is a 2-1/2" deep, gangable 1-gang switch box engineered for durable, code-compliant electrical rough-in work. Designed with a gangable side-knockout construction, this switch box allows installers to combine multiple units side-by-side to create multi-gang configurations on the job site, eliminating the need to stock separate multi-gang box SKUs. Integrated MC clamps are built directly into the box, providing a secure, fast termination point for armored (MC) cable without the need for separate connectors, saving installation time and reducing the parts count on every rough-in run. At 2-1/2" in depth, the GB-1-MC offers ample interior volume for switches, receptacles, and the associated conductors and devices typically installed in residential and light commercial branch circuits.

Key Features

  • Trade Size: 2-1/2" deep 1-gang switch box body sized for standard switch and receptacle device installations.
  • Gangable Design: Removable side plates allow multiple boxes to be joined together on site to form 2-gang, 3-gang, or larger multi-device configurations from a single box style.
  • Integrated MC Clamps: Factory-installed MC cable clamps provide a secure, code-recognized cable termination point without requiring separate add-on connectors.
  • Single-Gang Configuration: Sized and configured to accept standard single-gang switches, receptacles, and device plates.
  • Simplified Rough-In: Combining gangability with built-in cable clamps reduces the number of individual components electricians need to source, stock, and install for a given box configuration.

Orbit GB-1-MC – Frequently Asked Questions

1) What's the difference between the Orbit GB-1-MC and the GDB-1 switch box?
Both are gangable 1-gang steel switch boxes from Orbit, and the difference is depth. The GB-1-MC is the 2-1/2 inch deep version with integrated MC cable clamps built into the box. The GDB-1 is the 3-1/2 inch deep version, which gives you more interior volume for conductors and devices. If you're pulling MC cable and want the clamps already in the box, order the GB-1-MC; if box fill is your constraint, go deeper with the GDB-1.
2) Can I gang Orbit GB-1 switch boxes together to make a 2-gang or 3-gang box?
Yes. The Orbit gangable 1-gang switch box uses removable side plates, so you can join units side by side on the job to build 2-gang, 3-gang or larger multi-device configurations from one box style. That means you stock one SKU instead of separate multi-gang boxes for every opening.
3) Do I need separate MC connectors with the Orbit GB-1-MC box?
No. The GB-1-MC has factory-installed MC cable clamps inside the box body, giving you a code-recognized termination point for armored cable without buying add-on connectors. That drops the parts count on every rough-in run.
4) What is the closest alternative to the Orbit GB-1-MC gangable 1-gang steel switch box?
The nearest equivalent is the Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box, a 1-gang gangable switch box in pre-galvanized steel. Both are single-gang gangable steel boxes that can be joined side by side for multi-device configurations. The difference is cable termination and depth: the Orbit GB-1-MC is 2-1/2 inches deep with factory-installed MC cable clamps built into the box, while the Steel City Adjust-A-Box is an adjustable-style box for setting box depth relative to the finished wall. If your rough-in is MC cable and you want the clamp integral to the box, the Orbit box keeps the connector count down; if you need to dial in depth over varying wall thicknesses, the Steel City box is the one to look at.
5) How many boxes come in a case of the Orbit gangable switch box?
They ship 100 boxes per pack. For a rough-in crew that's enough to cover a full floor of device openings without reordering, and it's the quantity to plan around when you're pricing out a multi-unit or tract job.
6) Will the Orbit 1-gang box take a standard switch, receptacle and device plate?
Yes. It's configured as a single-gang box sized to accept standard single-gang switches, receptacles and device plates, so no special trim is needed. Standard device screw spacing applies.
7) What else could I use instead of the Orbit gangable steel switch box?
If you want another gangable steel 1-gang box, the Thomas and Betts LXWOWC-25 Steel City Adjust-A-Box is a pre-galvanized steel gangable 1-gang box. If the job calls for non-metallic, Allied Moulded makes the FlexBox Series thermoplastic switch box, and the 4304-NK is a 4-gang fiberglass reinforced thermoset polyester box when you need a one-piece multi-gang rather than ganging singles together.
8) Should I gang single boxes or buy a one-piece multi-gang box?
Ganging Orbit 1-gang boxes lets you decide gang count at the opening, which is handy on remodels where the device count changes after rough-in, and it means one SKU on the truck. A one-piece box is the better call when the gang count is fixed on the drawings and you want fewer seams to seal, for example the Allied Moulded 4304-NK 4-gang fiberglass box for a non-metallic four-device opening.
9) I need a nonmetallic switch box instead of a steel one. What should I use?
Orbit's gangable switch boxes are steel-bodied boxes with integrated MC clamps and removable side plates. If the job calls for a nonmetallic box, the Allied Moulded FlexBox Series thermoplastic switch box is the direct change of material, and the Allied Moulded 4304-NK is a fiberglass reinforced thermoset polyester box in a 4-gang configuration. Note that moving to a nonmetallic box changes how you handle cable entry and bonding, since you lose the factory MC clamps that come built into the Orbit box.
10) If I need a 4-gang box, is it better to gang Orbit boxes or buy a one-piece 4-gang box?
Both routes work. The Orbit 1-gang boxes have removable side plates so you can join four of them on site to build a 4-gang opening from one stocked box style, which is why they ship in a 100-pack. The alternative is a factory one-piece unit such as the Allied Moulded 4304-NK, a 4-gang fiberglass reinforced thermoset polyester box, which arrives as a single assembly with no gang seams to make up in the wall. Ganging Orbit boxes gives you flexibility to build 2-gang, 3-gang, or larger from the same inventory; the 4304-NK fixes the configuration at four gangs and is nonmetallic.
11) Does the Steel City Adjust-A-Box accept MC cable the same way the Orbit box does?
Not in the same way. The Orbit GB-1-MC has MC cable clamps factory-installed in the box body, so armored cable terminates without a separate connector. The Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is listed as a pre-galvanized steel 1-gang gangable switch box, so plan on the cable connector being a separate line item on your takeoff. If you are running MC throughout and want to cut the connector count on every rough-in, that is the point of difference to weigh.
12) Is this Orbit box suitable for commercial work or only residential?
Both. The box is intended for residential switch and receptacle rough-in and for light commercial branch circuit wiring, including new construction and remodel work. For heavier commercial MC runs it's the clamp version you want, since the clamps terminate armored cable at the box.
13) I need extra box volume for a device with a lot of conductors. What are my options?
Orbit offers the same gangable 1-gang body in two depths, 2-1/2 inch and 3-1/2 inch, and stepping to the 3-1/2 inch GDB-1 is the simplest way to pick up interior volume without changing the device opening. If the conductor count is driven by multiple devices rather than one crowded single gang, a one-piece 4-gang unit such as the Allied Moulded 4304-NK fiberglass reinforced thermoset polyester box spreads the devices and conductors across four gangs instead.
