Gently Removing an Electrical Box Punchout

[BLLG]

Sorry, if you are using a hammer and screwdriver you are working to hard. I use a screwdriver and my linesman pliers and where there is little clearance I grab the my flat nose pliers. This method works where there is less clearance than using a clamp. I can do that faster than you can get the clamp screwed on. Of course I have forty years of experiance and thousands of KO's.
