Electrical box cover · 4 in square · centre knockout · Vista 20116
SKU: VISTA-20116
4 in square steel electrical box cover with centre knockout for closing or adapting a standard 4 in junction box. Commonly used where a centred wiring or connector entry is needed in commercial, industrial, or residential rough-in work.
What this product is for
This 4 in square electrical box cover is used to close and protect a standard 4 in square junction box while providing a centre knockout for a connector, fitting, or cable entry where permitted by the installation design and local code.
Use for
Use for 4 in square steel boxes in exposed or concealed wiring systems, junction boxes, and service access points where a flat cover with centred access is required. Suitable for many contractor and maintenance applications in residential, commercial, and light industrial work.
Avoid for
Avoid using this cover on boxes that are not standard 4 in square, on device openings that require a raised device cover, or where a blank cover without knockout is required. Always confirm box compatibility, fitting size, and code requirements before installation.
Best for
Best for electricians needing a simple 4 in square cover with a centred knockout for a clean box closure and straightforward field installation.
Installed in
Typically installed on 4 in square junction boxes in walls, ceilings, utility spaces, service rooms, workshops, and commercial fit-outs. A 4 in box size is approximately 102 mm square.
Why this product exists
It provides a practical way to protect splices and close a junction box while allowing a centred opening for a fitting or cable path, reducing the need for field modification when a knockout cover is the correct box accessory.
Compared with similar products
Compared with a blank 4 in square cover, this version adds a centre knockout for more flexible box termination. Compared with raised device covers, it is intended for box closure rather than mounting a switch or receptacle. Typical 4 in square covers in this class are steel and sized for standard 4 in boxes.
