Greenlee Knockout Punches Editorial Review
The Greenlee 721-12 Punch is designed to make 7/8" inch holes for 1/2" conduit. One customer replaced a broken knockout with it and it worked fine. Several customers found it easy to install, though one recommended going to a tire shop for help. The tires are well-suited for everyday riding and desert terrain, providing good traction and improved clearance. They are also six-ply and long-lasting. However, one customer noted that the tires had less rubber compared to air, and another said that shipping took longer than expected. Overall, the Greenlee 721-12 Punch has received positive reviews for its quality, price, and effectiveness.
