Greenlee 1431AV 3 Conduit Size Standard Round Knockout Punch

Using the Greenlee 1431AV is straightforward. First, make sure you're using it with the 2-1/2' - 4' Conduit Size Manual Round Standard Knockout Punch Kit 7304. It's only the punch, so you'll need the rest of the kit components. When using, position it properly on the material where you want to create the 3' conduit size hole (which will end up being 3-1/2' in size). Be careful while operating to avoid any accidents. As for maintenance, keep it clean after each use. Wipe off any debris or dust. Store it in a dry place to prevent rusting. If you notice any signs of wear or damage, it's a good idea to get it checked or replaced to ensure its continued performance.
