Round Center Opening – Designed for Dedicated Devices

This cover features a round center opening (1.405 diameter), making it ideal for applications where a single, dedicated device is required. It is commonly used for single receptacles, special-purpose outlets, and push buttons or control devices where a centered, clean installation is preferred.

The centered round opening allows proper alignment and clearance for devices that are not part of a duplex configuration. This makes it a practical choice for dedicated power circuits, controlled loads, and equipment connections where only one device is intended to be installed in the box.
