Concentric knockouts (KO's) ready for removal.

A concentric knockout being removed from the bottom of a Square D QO Load Center. This looks like the 3/4″ knockout is punched inward.

My Knipex Diagonal Pliers cutting through the mild steel concentric knockout. I think this is the 1" Knockout.
All of the unnecessary concentric knockout rings have been removed. A 1 1/4" connector will be going into this knockout.
