Square Box Cover · 1 Device · 1/2 in Raised for 4 in Box · Vista 20133
Raised square box cover for mounting one device on a 4 in box, with 1/2 in raised depth for extra wiring space. Commonly used on exposed work and commercial box installations where device clearance is needed.
What this product is for
This raised square box cover is used to mount one wiring device on a 4 in square electrical box. The 1/2 in (13 mm) raised profile helps provide additional device and conductor space at the box face.
Use for
Use for commercial, industrial, and exposed work box installations where a single device must be mounted on a 4 in square box. Typical applications include surface-mounted wiring systems and box assemblies that need extra face depth.
Avoid for
Avoid using this cover where a flat cover, blank cover, or a different device opening is required. Confirm device style and box size before ordering.
Best for
Best for electricians matching a 4 in square box with a 1-device raised cover when additional front depth is needed for wiring or device fit-up.
Installed in
Typically installed in commercial walls, service spaces, utility areas, workshops, and other exposed conduit or surface raceway installations using 4 in square boxes.
Why this product exists
Raised covers let the device mount directly to the cover while adding working depth at the face of the box. This is commonly used when a standard flat cover will not provide enough clearance for the device or conductors.
Compared with similar products
Compared with a flat 4 in square cover, this 1/2 in raised version provides more front clearance. Compared with 3/8 in raised covers, it offers slightly more depth for device fit. Actual box fill and suitability depend on the installed device, conductor count, and local electrical code.
