Orbit GB-1-NM 1-Gang Switch Box, 2-1/2" Deep, Gangable, with NM Cable Clamps

The Orbit GB-1-NM 1-Gang Switch Box, 2-1/2" Deep, Gangable, with NM Cable Clamps is a rugged electrical outlet box built for switch and device installations in residential and light commercial wiring. This 2-1/2" deep gangable box allows installers to combine multiple boxes side-by-side to form 2-gang, 3-gang, or larger multi-device assemblies without needing to stock separate multi-gang box sizes, streamlining inventory and simplifying rough-in work. Integrated NM cable clamps are built into the box to secure non-metallic sheathed cable directly at the point of entry, reducing strain on conductors and helping maintain a clean, code-conscious termination inside the enclosure. The added depth of 2-1/2" provides generous interior volume for wire fill and device connections compared to shallower boxes, giving electricians more working room when installing switches, dimmers, or other single-gang devices.

Key Features

  • Box Depth: 2-1/2" deep design provides extra interior volume for wire fill and device installation.
  • Gangable Construction: Sides remove or interlock so multiple boxes can be joined together to build 2-gang, 3-gang, and larger switch box assemblies on the job site.
  • Integrated NM Cable Clamps: Built-in clamps secure non-metallic sheathed cable at the point of entry, protecting conductors from abrasion and pull-out.
  • 1-Gang Configuration: Sized to accept a single switch, receptacle, or device before ganging with additional boxes.
  • Durable Steel Construction: Built to withstand the rigors of new construction and remodel wiring installations.
  • Jobsite-Ready Design: Simplifies rough-in by letting electricians build the exact box size needed on site rather than stocking every multi-gang variant.

Technical Specifications

  • Depth: 2-1/2"
  • Configuration: Gangable, 1-Gang
  • Cable Entry: Integrated NM cable clamps

Typical Applications

  • Residential Switch and Receptacle Installations
  • New Construction Wiring
  • Remodel and Retrofit Electrical Work
  • Multi-Gang Switch and Device Assemblies
  • Non-Metallic Sheathed Cable (NM) Wiring Systems

Orbit GB-1-NM – Frequently Asked Questions

1) Can the Orbit GB-1-NM switch box be ganged together to make a 2-gang or 3-gang box?
Yes. The GB-1-NM is a gangable 1-gang steel box, so the sides remove or interlock and you can join boxes side by side to build 2-gang, 3-gang, or larger device assemblies on site. That means you only have to carry one box instead of every multi-gang size. Each box on its own accepts a single switch, receptacle, or dimmer before ganging.
2) Do I need separate cable connectors for the Orbit GB-1-NM, or are clamps built in?
Clamps are built in. The GB-1-NM has integrated NM cable clamps that secure non-metallic sheathed cable right at the entry point, so you are not buying and installing separate NM connectors for each knockout. The clamps hold the sheath against pull-out and keep the conductors off the metal edge.
3) How deep is the Orbit GB-1-NM switch box, and why would I pick it over a shallower box?
The GB-1-NM is 2-1/2 inches deep. The extra depth over a shallow box gives you more interior volume for wire fill and more room to fold conductors behind a switch or dimmer, which matters when you have multiple cables landing in one box. If you need still more volume, the same family is offered in a 3-1/2 inch depth.
4) Is the Orbit GB-1-NM steel box right for NM (Romex) wiring, or do I need a different box?
It is built for NM systems. The clamps in the GB-1-NM are NM cable clamps, so non-metallic sheathed cable is the intended wiring method, in residential and light commercial rough-in. If you are pulling MC or armored cable instead, that calls for a box with clamps rated for that cable rather than the NM version.
5) What is the closest alternative to the Orbit GB-1-NM if I need a 1-gang gangable steel switch box?
The Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is a 1-gang gangable switch box in pre-galvanized steel, so it covers the same single-device, gang-it-on-site role as the Orbit GB-1-NM. The difference is cable entry: the GB-1-NM has integrated NM cable clamps built into the box to secure non-metallic sheathed cable at the point of entry, while the Steel City box is identified as an Adjust-A-Box, a design whose depth adjusts in the wall. Choose the Orbit when you want the clamps already in the box for NM rough-in.
6) I need a 4-gang switch box and do not want to gang boxes together. What should I use instead of the Orbit GB-1-NM?
Use the Allied Moulded 4304-NK, a 4-gang switch box molded from fiberglass reinforced thermoset polyester. It arrives as one four-device enclosure, so there is no ganging step on site. The Orbit GB-1-NM takes the other approach: it is a 1-gang box whose sides remove or interlock so you build 2-gang, 3-gang, or larger assemblies from stock on the job. If the opening is a fixed four-device bank, the single molded box is the simpler build.
7) Is the Orbit GB-1-NM sold individually or by the case?
It ships as a pack of 100 boxes. That is a rough-in quantity, sized for a house or a light commercial floor rather than a single device replacement.
8) What is the difference between the 2-1/2 inch and 3-1/2 inch Orbit gangable box options?
Depth and part number. The 2-1/2 inch box is the GB-1-NM with NM cable clamps. The deeper 3-1/2 inch option is the GDB-1-MC-FB. Pick the 2-1/2 inch where stud depth or insulation leaves you tight, and the deeper box where you have several cables and a bulky device to fit.
9) Is there another steel gangable 1-gang box I could use instead of the Orbit GB-1-NM?
The Thomas & Betts LXWOWC-25, a Steel City Adjust-A-Box 1-gang gangable box in pre-galvanized steel, is the closest steel equivalent. Difference to note: the Orbit GB-1-NM comes with NM cable clamps built in, so if you want integral clamping rather than adding connectors, that is the deciding point.
10) Is a nonmetallic switch box a substitute for the Orbit GB-1-NM?
Not a direct one. The Allied Moulded FlexBox Series switch box is thermoplastic and the Allied Moulded 4304-NK is fiberglass reinforced thermoset polyester, while the Orbit GB-1-NM is steel. A nonmetallic box takes a different fastening and bonding approach than a steel box and does not gang the way the GB-1-NM does, whose removable interlocking sides let you build multi-device assemblies on site. If the spec on the drawing calls for a steel gangable box with NM clamps, the nonmetallic boxes are not interchangeable with it.
11) Can I use the Orbit GB-1-NM on a remodel, or is it only for new construction?
Both. The GB-1-NM is used in new construction rough-in and in remodel and retrofit wiring, for switches, receptacles, and multi-gang device assemblies on NM cable systems.
12) If I am buying in bulk for a tract build, how does the Orbit GB-1-NM compare to the Steel City LXWOWC-25 for stocking?
The Orbit GB-1-NM ships 100 boxes to the pack, and because the 1-gang box gangs into 2-gang, 3-gang, and larger assemblies, one SKU covers most device locations in a house instead of stocking every multi-gang size. The Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is also a 1-gang gangable box, so it stocks the same way, but it is an adjustable-depth design rather than a fixed-depth box with integrated NM clamps. Orbit also offers the GB-1-NM opening in a 3-1/2 inch size if you need deeper boxes on the same job.
