Review on Morris Products 21722 Plastic Knockout: Durable and Efficient Solution for Electrical Installations by Nathan Jones

Revainrating 4 out of 5

The price is right.

They don't always fit the standard 1/2 KO hole but are much cheaper to use than the metal parts. (They also fit the PVC clutch hub pretty snugly, in case anyone is interested.)

Pros
  • Weight
Cons
  • Some small things
