I need to cut a square hole ( 1" x 1.25" ) in a standard plastic
electrical box cover ... in this case, its the type with one hole for a TV
jack. The new square hole will be to mount a chassis jack for Anderson
Power Pole connections. ( Powerwerx HS-4 ).


Can anyone advise of the best method and tool to do this? I am concerned
about cracking the plastic if I don't do it right.
