Greenlee 7240SB Panel Builder Knockout Kit (1/2, 3/4, 30mm)

Using the Greenlee 7240SB Panel Builder Knockout Kit is straightforward. First, select the appropriate punch and die for the size you need. Place the material you're working on between the punch and die. Then, use the manual ratcheting driver along with the draw studs to create the knockout. When using the kit, make sure to wear appropriate safety gear like gloves and goggles. Always check the material thickness to ensure it's within the 16 - 14 gauge mild steel range the kit is designed for. For maintenance, after each use, wipe down the punches, dies, and draw studs to remove any debris. Store the kit in the provided case to keep all the parts organized and protected. This will help keep your kit in good working condition for a long time.
