Description

Hubbell CFBKOPLATECR Knock Out Plate

Overview

The Hubbell CFBKOPLATECR is a corrosion-resistant knock out plate designed to provide versatile conduit entry points for standard electrical boxes. This plate addresses the need for secure and adaptable wiring transitions in commercial and industrial installations, ensuring a clean and protected connection for various conduit sizes. The CFBKOPLATECR is engineered for durability and ease of installation, making it a practical component for any electrical system requiring reliable conduit management.

Compatibility

This knock out plate is designed to fit standard electrical boxes and is compatible with conduit sizes of 3/4 inch, 1 inch, and 1-1/4 inch. It provides multiple KO (knock out) options to accommodate different wiring configurations and conduit types commonly used in security and electrical infrastructure deployments.

Installation Notes

Installation involves removing the existing blank plate or knock outs from the electrical box and securing the CFBKOPLATECR in its place. The pre-stamped knock outs can be cleanly removed using appropriate tools, such as a hammer and punch or a knockout punch set, to accept the desired conduit size. Its corrosion-resistant material ensures longevity even in environments prone to moisture or chemical exposure.
