Greenlee 1430AV 2-1/2 Conduit Size Standard Round Knockout Die

Using the Greenlee 1430AV is easy. First, make sure you have the 2 - 1/2' - 4' conduit size manual round standard knockout punch kit 7304. Then, simply insert the die into the appropriate place in the kit. When using, apply even pressure to create the knockout. As for maintenance, after each use, clean the die to remove any debris. Store it in a dry place to prevent rust. Note that this is only the die, so you need the full kit for it to work properly.
