Review on 53151 Pre Galvanized Square Extension Knockouts by David Batte

Revainrating 5 out of 5

Well made, good fit.

That's what it should be, a standard extension. It includes screws and is made of heavy duty galvanized steel. As always, watch out for sharp edges (like any other box).

Pros
  • UL Listed
Cons
  • Very Expensive
