RACO 561 2-3/4" Deep Switch Box with 1/2" Knockouts, Pack of 100
The RACO 561 is a 2-3/4" deep switch box built to house standard wiring devices such as switches and receptacles in everyday electrical installations. Featuring 1/2" knockouts positioned for conduit and cable connector entry, this box allows electricians to route wiring into the enclosure quickly and cleanly during rough-in work. The 2-3/4" depth provides generous interior space for making up connections, splicing conductors, and mounting devices without overcrowding the box. Sold in bulk packs of 100, the RACO 561 switch box is well suited for contractors, electrical wholesalers, and property managers who need a dependable, ready-to-stock supply of standard switch boxes for residential and light commercial projects.
Key Features

- 1/2" Knockouts: Pre-formed 1/2" knockouts are positioned for straightforward conduit, cable clamp, or connector entry, reducing on-site fabrication time.
- Switch Box Configuration: Designed as a single-device switch box, the 561 is sized to accept standard toggle switches, receptacles, and similar wiring devices.
- Bulk Pack of 100: Supplied in cartons of 100 units, this switch box is packaged for high-volume rough-in work, new construction, and large remodel jobs.
- Consistent, Repeatable Sizing: Uniform 2-3/4" depth and 1/2" knockout placement across every box in the pack help crews standardize their rough-in process from box to box.

RACO RACO561 – Frequently Asked Questions
1) What size is the RACO 561 switch box and how deep is it?
The RACO 561 is a single-device steel switch box measuring 2 x 3.375 x 2.75 inches, with the 2.75 inch figure being the box depth. That depth is what gives you room to make up splices behind a switch or receptacle instead of fighting the device back into a shallow box.
2) Does the RACO 561 take 1/2 inch conduit or cable connectors?
Yes. The 561 comes with pre-formed 1/2 inch knockouts placed for conduit, cable clamp, or connector entry, so standard 1/2 inch EMT connectors and 1/2 inch NM cable connectors land straight in with no drilling on site.
3) Will the RACO 561 work in a steel stud or metal framed wall with conduit?
It is a steel box with 1/2 inch knockouts, so it is the right family for metal stud and conduit work where a non-metallic box would not carry the raceway. If you need a box made specifically for steel studs on a non-metallic system, the Cantex EZ20SB EZ Box 1-gang non-metallic steel stud box is the alternative we carry.
4) Should I use a steel switch box like the RACO 561 or a plastic one?
Pick steel when you are running conduit or armored cable and need the raceway bonded through the box, or where a metal enclosure is called for. Go non-metallic when you are pulling NM cable in wood framing and want a lighter, cheaper box. For that side, we carry the Allied Moulded P-181 FlexBox 1-gang thermoplastic switch/receptacle box at 18 cubic inches and the Allied Moulded 2302-NKV fiberglass reinforced 2-gang box.
5) Can I gang two RACO 561 boxes together for a two-switch opening?
The 561 is a single-device box sized for one toggle switch or receptacle, so for a two-device opening you want a two-gang box rather than this one. The Allied Moulded 2302-NKV is a 2-gang box we stock, or the Thomas and Betts LXWOWC-25 Steel City Adjust-A-Box is a gangable 1-gang steel box if you prefer to build the gang up.
6) What is a non-metallic alternative to the RACO 561 switch box for residential rough-in?
The Allied Moulded P-181 FlexBox is a 1-gang thermoplastic switch/receptacle box with 18 cubic inches of volume, used for residential switch and receptacle work. The RACO 561 is a steel switch box 2-3/4 inches deep, 3-3/8 inches high and 2 inches wide with 1/2 inch knockouts for conduit or cable connector entry. The practical difference is material and wiring method: the steel 561 accepts conduit and metal cable connectors through its knockouts, while the thermoplastic FlexBox is a non-metallic box for non-metallic cable.
7) I need a two-gang box instead of the single-gang RACO 561 - what should I use?
The RACO 561 is a single-device switch box sized for one toggle switch or receptacle, 2 inches wide. For a two-device opening, the Allied Moulded 2302-NKV is a fiberglass reinforced 2-gang electrical switch box. Note the change in material as well as gang count: the 561 is steel with 1/2 inch knockouts, while the 2302-NKV is a fiberglass reinforced non-metallic box.
8) What is the closest steel equivalent to the RACO 561 from another brand?
The Thomas and Betts LXWOWC-25 Steel City Adjust-A-Box is the nearest steel peer: a 1-gang gangable switch box in pre-galvanized steel. Like the RACO 561 it is a single-device steel box for switches and receptacles. The 561 is a 2-3/4 inch deep box with 1/2 inch knockouts and a gray finish; the Steel City box is gangable, meaning its sides come off so boxes can be joined for multi-device assemblies.
9) Is the RACO 561 box UL Listed for commercial work?
The 561 switch box is UL Listed, and it is intended for residential and light commercial wiring, including new construction rough-in and remodel work.
10) I need a box that adjusts for drywall depth after the rough-in. Is the RACO 561 that box?
No. The 561 is a fixed-depth 2.75 inch steel switch box, set once you nail or screw it in. If you need the face to move to match finished wall thickness, the Thomas and Betts LXWOWC-25 Steel City Adjust-A-Box, a pre-galvanized steel 1-gang, is the adjustable option we carry.
11) Can I use the RACO 561 in a metal stud wall, or is there a box made for that?
The RACO 561 is a general-purpose steel switch box 2-3/4 inches deep with 1/2 inch knockouts, intended for standard residential and light commercial rough-in. If the detail calls for a box designed around steel studs specifically, the Cantex EZ20SB EZ Box is a 1-gang non-metallic steel stud box built for that framing. Choose on wiring method too: the 561 is steel and takes conduit or cable connectors through its knockouts, the EZ20SB is non-metallic.
12) What is the exact part number and finish on the RACO 2-3/4 inch deep switch box?
Order it as RACO model 561. It is a gray steel box, 2.75 inches deep, sold 100 to a pack.
