Electrical Box with Knockouts

Electrical Knockouts

Electrical knockouts (EKO) are often overlooked, yet part of our everyday life. They’re tucked away – the unsung heroes of the electrical arena. Thanks in part to EKOs, our world can be turned on and off with the flip of a switch.

Sheet metal electrical boxes serve as a hub or protective barrier to support an electrical application. Knockouts are strategically punched into electrical boxes, allowing conduit to be fed through or switches to be installed with a secure fit. Simply punch out the holding tabs to access the hole that corresponds closely with the size of your conduit and feed it through. Electrical knockouts provide a clean, finished look and a snug fit.
