Greenlee 7310 hydraulic knockout punch kit. Has punches and dies from 1/2" to 4" it is missing the 3/4" die. Comes with the several manual mandrels, the cylinder and the Greemlee 767 pump. I got it off an electrician that owed me back rent years ago, I never used it. It may need some of Greenlees fluid in it but it does function. Just one of the larger punches goes for $300-$400 each. Asking $300. Call or text Rick 785-569-double7 double8
