Not sure if this cover plate matches your existing box dimensions or knockout requirement? Send us your box specs and we'll confirm the fit.

The SMP20124 is sized for a standard 4" × 2½" rectangular electrical box. Always verify your box's face dimensions before ordering — if you're unsure, send us your box model or dimensions and we'll confirm compatibility.

The 1-13/32" knockout hole is sized to accept a standard conduit connector or device fitting of that diameter (the 11C3 designation refers to this specific knockout size). It allows a conduit or cable connector to pass through the cover while keeping the box securely closed and protected.

The SMP20124 is a standard metal cover plate intended for general indoor residential and commercial junction box applications. For damp or wet locations, a weatherproof or listed wet-location cover rated for those conditions should be used. Contact our team if you need guidance on the right cover for your environment.
