USA-Made Raised Single Receptacle Circular Covers for 4x4 Steel Electrical Boxes
These raised steel covers are designed specifically for single round receptacles and are engineered to fit 4-inch square metal electrical boxes used in exposed-work installations. The covers include crushed corners for a precise and secure fit on both drawn and welded 4x4 metal boxes, allowing a single receptacle device to mount directly onto the raised cover while leaving room inside the box for wiring, junctions, and splicing.
Premium Single Receptacle Covers for Exposed-Work Electrical Systems
This collection features USA-made raised steel covers designed for NEMA-style single receptacles, including round industrial or commercial-style outlets. These are functional device-mounting covers, enabling electricians to mount a single receptacle directly to the cover, which then installs onto the 4x4 box for a clean, rigid, and code-compliant exposed-work installation.
Built for 4x4 Metal Boxes
All covers in this collection are designed to fit:
- 4x4 drawn steel boxes
- 4x4 welded steel boxes
- 4-inch square metal junction boxes used with EMT, rigid, or MC conduit systems
The covers include crushed corners to ensure strong metal-to-metal seating, perfect alignment, and secure installation in demanding environments.
When Are Single Receptacle Raised Covers Used?
Raised single-receptacle covers are used whenever a single round receptacle needs to be installed onto a surface-mounted 4x4 metal electrical box. These types of wiring devices are usually meant when there is a need for dedicated power for specialized and heavy-duty machinery and equipment. They provide the correct raised depth and precise round opening required for these devices while enabling the box to function as a junction point for wire splicing or circuit transitions.
These covers are commonly used in exposed-work installations, where conduit systems run on the surface of the wall and devices are installed directly on metal boxes rather than recessed into the wall.
Typical applications include:
- Industrial machinery or equipment receptacles
- Commercial buildings, factories, and warehouses
- Workshops, production floors, and utility rooms
- Mechanical areas and electrical rooms
- Basements, garages, and service areas needing durable single outlets
Unlike blank covers or multi-device raised plates, these are engineered specifically for single round receptacles, offering a professional, secure, and code-compliant exposed-work installation.
