Greenlee K3BB-3 3 Conduit Size Manual Knockout Set

Using the Greenlee K3BB-3 Manual Knockout Set is a breeze. First, make sure you've got the right punch and die for your 3-inch conduit. The laser markings will help you quickly pick the correct parts. Once you've selected them, use the manual draw stud to secure the punch and die to your manual tool. Align the set on the conduit according to the alignment markings for accurate results. When using the set, don't force it too hard as it's designed to work smoothly with the manual tool. For maintenance, after each use, clean the punch and die with a dry cloth to remove any debris. Keep them in a dry place to prevent rusting. And remember, this set replaces the 739BB, so you're getting an updated and reliable product.
