RACO 440 3 in. x 2 in. Gangable Steel Switch Box, 2 in. Deep, AC/MC/Flex Clamps
The RACO 440 is a 3 in. x 2 in. gangable steel switch box with a 2 in. depth, built for switch, receptacle, and device installations in commercial and residential branch-circuit wiring. Because it is gangable, additional RACO 440 boxes can be joined side by side to form multi-gang assemblies without a separate multi-gang box, saving stock and simplifying rough-in. The box includes one 1/2 in. knockout along with factory AC/MC/Flex clamps for quick, secure connections to armored cable, metal-clad cable, or flexible conduit, and it is UL Listed for use in standard branch-circuit wiring systems.
Key Features
- Box Size: 3 in. x 2 in. footprint with a 2 in. depth for standard switch and device mounting.
- Durable Construction: Steel body for rigidity and long-term durability in rough-in wiring applications.
- Gangable Design: Sides remove to gang multiple RACO 440 boxes together for multi-device installations.
- AC/MC/Flex Clamps: Built-in clamps accept Armored Cable, Metal-Clad (MC) cable, and Flex conduit for secure, code-compliant terminations.
- Knockout: One 1/2 in. knockout for additional conduit or cable entry.
- Plaster Ears: Integrated plaster ears hold the box flush and properly positioned in plaster or drywall walls.
- Bracket Type: No bracket, suited for installations where the box is fastened directly without a mounting bracket.

RACO RACO440 – Frequently Asked Questions
1) Will the RACO 440 accept MC cable without a separate connector?
It has factory built-in AC/MC/Flex clamps, so armored cable, metal-clad cable (including MCI-A) and flexible conduit terminate directly in the box with no added connectors. There is also one 1/2 in. knockout if you need a conduit or cable entry beyond the clamps.
2) Does the RACO 440 come with a mounting bracket for stud work?
No bracket. The 440 is a no-bracket box, fastened directly to the stud or framing member through the box itself. If your rough-in calls for a bracketed or adjustable box, the Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is another gangable 1-gang steel switch box option.
3) Should I use a steel gangable box like the RACO 440 or a non-metallic box?
Go steel when you are running AC, MC or flex, because the 440's clamps are built for those wiring methods and the metal box bonds with the cable armor. Non-metallic boxes are the choice for NM cable work: the Allied Moulded P-181 FlexBox is an 18 cu. in. thermoplastic residential switch/receptacle box, and the Cantex EZ20SB EZ Box is a non-metallic 1-gang box made for steel stud framing. For a one-piece 2-gang non-metallic box, the Allied Moulded 2302-NKV is fiberglass reinforced.
4) What is the closest steel gangable alternative to the RACO 440 switch box?
The Thomas & Betts LXWOWC-25 Steel City Adjust-A-Box is the nearest steel equivalent - a 1-gang gangable switch box in pre-galvanized steel, so like the RACO 440 its sides come off to build multi-gang assemblies. The RACO 440 is a 2 in. deep steel box with factory AC/MC/MCI-A/Flex clamps and is UL Listed; the Adjust-A-Box name indicates an adjustable depth design, so confirm the depth setting you need for your wall before swapping.
5) What size is the RACO 440 switch box and how deep is it?
Footprint is 3 in. x 2 in. with a 2 in. depth, the standard single-device opening dimension for a switch or receptacle. The 2 in. depth is the deepest common gangable steel switch box, which is what you want when you are landing MC into the clamps and still have to fold a device and conductors back in.
6) Will the RACO 440 sit flush in a plaster or drywall wall?
It has integrated plaster ears, which set the box face at the correct depth and hold it flush in plaster or drywall construction. That is what positions the device ring correctly so the cover plate sits tight to the finished wall.
7) Is the RACO 440 approved for commercial branch-circuit wiring?
The 440 is UL Listed and intended for switch, receptacle and device installations on standard branch circuits in both commercial and residential work, new construction or remodel.
8) I need a 2-gang box for two switches. Do I buy two RACO 440s or a single 2-gang box?
Either works. Two 440s ganged together give you a 2-gang opening and keep your stock to one part number, which is how most electricians run it on AC/MC jobs. If you would rather use a single one-piece 2-gang box, the Allied Moulded 2302-NKV is a fiberglass reinforced 2-gang switch box.
9) Do I need two RACO 440 boxes or a 2-gang box for a two-switch opening?
Either approach works. Two RACO 440 boxes gang together side by side because the box is gangable, so you stock one part for single and multi-device openings. If you would rather set one enclosure, the Allied Moulded 2302-NKV is a one-piece fiberglass reinforced 2-gang switch box. The difference is material and method: the 440 is steel with AC/MC/MCI-A/Flex clamps, the 2302-NKV is a non-metallic 2-gang body.
10) What should I use instead of the RACO 440 when mounting to a steel stud?
The RACO 440 is supplied with no bracket, so it is fastened directly to the framing member. If your opening is a steel stud and you want a box designed for that attachment, the Cantex EZ20SB EZ Box is a 1-gang non-metallic steel stud box. Note the trade-off: going to the EZ20SB moves you from a steel box with AC/MC/MCI-A/Flex clamps to a non-metallic enclosure.
11) Is the Allied Moulded 2302-NKV a drop-in replacement for the RACO 440?
No. The 2302-NKV is a 2-gang fiberglass reinforced box, while the RACO 440 is a 3 in. x 2 in. single-gang steel box 2 in. deep with plaster ears and one 1/2 in. knockout. The gang count, the wall cutout, and the material all differ, and the 440's integral AC/MC/Flex clamps have no counterpart in a non-metallic body. Treat it as a different opening, not a swap.
12) What is the manufacturer part number for the RACO 3 x 2 x 2 gangable switch box with AC/MC clamps?
RACO 440. That is the full part number for the 3 in. x 2 in. by 2 in. deep gangable steel switch box with AC/MC/Flex clamps, one 1/2 in. knockout and plaster ears.
