RACO 192SM 4-Square Surface-Mount Electrical Box, 1-1/2" Deep
This RACO surface-mount electrical box features a 4-square (4SQ) body with a 1-1/2" deep (1-1/2D) profile, built to house conduit entries, wiring devices, and splice connections along exposed conduit runs. Its square, surface-mount configuration allows the box to be secured directly to a wall, ceiling, or structural surface rather than recessed into a wall cavity, making it a practical fit for surface conduit systems in commercial, industrial, and utility environments. The 4-square footprint pairs with standard 4-square covers, blank plates, and device rings, giving installers flexibility to configure the box for junction, pull, or device applications. As part of the RACO line of electrical boxes and conduit fittings, this surface box is built for field installation on exposed raceway systems where recessed boxes are not practical.
Key Features
- 4-Square Configuration: The 4SQ body provides a standard square footprint compatible with common 4-square covers, plaster rings, and device mounting hardware.
- 1-1/2" Deep Body: The 1-1/2D depth offers interior volume for conduit entries, splices, and wiring device connections within the box.
- Surface-Mount Design: The surface-mount (SM) configuration is intended for installation on the surface of a wall, ceiling, or structure rather than recessed mounting, simplifying installation on exposed conduit runs.
- Standard Cover Compatibility: Accepts standard 4-square blank covers, device plates, and mudrings, allowing the box to be configured for junction, pull, or device applications.
- Field-Ready Sizing: Dimensions are sized for direct surface mounting on exposed conduit runs without additional recessed-box hardware.
- RACO Build: Manufactured as part of RACO's line of electrical boxes and conduit fittings for professional electrical installations.

RACO 192SM – Frequently Asked Questions
1) What is a 4-square surface-mount box like the RACO 192SM used for?
The RACO 192SM is a 4-square box with a 1-1/2 inch deep body that mounts on the face of a wall, ceiling, or structure instead of being recessed into a wall cavity. It's the box you use on exposed conduit runs, where the raceway is run on the surface and the box has to sit out with it. Typical uses are junction and pull points, splice connections, and mounting wiring devices along surface conduit in commercial, industrial, and utility spaces.
2) Will standard 4-square covers and mudrings fit the RACO 192SM?
Yes. The 192SM uses the standard 4-square footprint, so it takes common 4-square blank covers, device plates, plaster rings, and mudrings. That's what lets you set it up as a junction box, a pull box, or a device box depending on what cover you put on it. The cover or ring is ordered separately from the box.
3) Can I recess the RACO 192SM into a stud wall?
No. This one is built as a surface-mount box, meant to be fastened to the face of a wall, ceiling, or structural surface. For a wall cavity behind drywall you want a recessed 4-square box with bracket or nail-on mounting instead. If the conduit is exposed and the box has to sit proud of the surface, the 192SM is the right configuration.
4) What is the difference between the RACO 192SM surface box and a Thomas & Betts Red-Dot 2IH3-2 box?
They solve surface wiring in two different ways. The RACO 192SM is a 4-square (4SQ) surface-mount body 1-1/2 inches deep, sized to accept standard 4-square blank covers, device plates, and mudrings so it can be set up as a junction, pull, or device box on an exposed conduit run. The Thomas & Betts Red-Dot 2IH3-2 is a 2-gang RT box supplied with three 3/4 inch hubs, so the conduit entries are integral to the casting rather than being made through a square box body. Choose the 192SM when you want the 4-square footprint and the flexibility of standard 4-square cover and ring accessories; choose the hubbed 2-gang Red-Dot box when you want a two-gang enclosure with 3/4 inch hubs already provided.
5) How do I order the RACO 192SM, and what part number should I give my supplier?
Order it by the RACO manufacturer part number 192SM. It ships as the box body only, so add the cover, blank plate, device ring, and any conduit fittings or connectors you need for the entries on your run as separate line items.
6) Is the RACO 192SM suitable for a retrofit where I can't open the wall?
That's one of the situations it's made for. Because the 192SM mounts to the surface, you can add a junction point or a device location on an existing wall or ceiling without cutting into the cavity, running the circuit in exposed conduit to the box. The description calls out renovation and retrofit wiring along with exposed runs in utility and mechanical areas.
7) Can a Red-Dot 2IH3-2 be used as a drop-in replacement for a RACO 192SM?
Not as a direct swap. The RACO 192SM is a 4-square surface box, so its cover, plaster ring, and device plate all follow the standard 4-square pattern and its mounting footprint is square. The Red-Dot 2IH3-2 is a 2-gang RT box with three 3/4 inch hubs, so it uses two-gang covers and its conduit entries are fixed at three 3/4 inch hub locations. Replacing one with the other means changing the cover and reworking the conduit entries, so confirm the existing cover type and where the raceway lands before substituting.
