*This punch is not required if you are building from one of our control panel kits and you opted to have use pre-punch the enclosure for you.
A GreenLee punch (shown in picture) is highly recommended. It produces a perfectly round and clean hole, free of any burrs or rough edges. We do not recommend using regular bits, step bits, or hole saws to make precision holes.
Make sure to use the exact part recommended here. You need a 1/2" conduit punch which makes a 7/8" diameter hole. Do not use a 1/2" chassis or radio punch.
