Not sure if this cover plate suits your specific box type or application? Send us your box model or project details and we'll confirm the fit.

The KORA SMP20102 is designed to fit standard 4" round electrical boxes, which are commonly used as junction boxes or fixture mounting boxes in walls and ceilings. Always verify your box's outer dimensions before ordering to ensure a proper fit.

The 1/2" knockout is optional — it can be left intact if you simply need a fully blank cover, or knocked out if you require a conduit fitting or cable connector pass-through. This makes the SMP20102 flexible for a variety of residential and commercial wiring applications.

Yes — the SMP20102 is well suited for replacement use. As long as your existing box is a standard 4" round type, this cover plate should drop right in as a direct replacement. If you're unsure about compatibility with your specific installation, feel free to reach out to us and we'll help confirm.
