Greenlee 2981AV – Frequently Asked Questions

1) Is the Greenlee 2981AV a complete knockout punch set or just the die?
It is a replacement die only, the 3-1/2 inch round die half of a knockout punch assembly. You order it to replace a worn or damaged die in a set you already own, so you will still need the matching punch, draw stud and driver to make a hole. The die is marked with its catalog number so you can identify it quickly in a case full of loose parts.
2) Will this Greenlee 3-1/2 inch round die punch through 10 gauge steel enclosure walls?
Yes. The die is rated for mild steel up to 10 gauge, which covers typical panel and enclosure sheet metal. It also punches aluminum, fiberglass and plastic. It is not rated for stainless steel, so for stainless enclosures use a die specifically rated for that material.
3) What driver can I use with the Greenlee 2981AV replacement die?
The die works with battery-powered, hydraulic, ratchet or manual drivers, so it fits whichever punch driver your crew already runs rather than locking you into one tool type.
4) Which Greenlee part number do I order for a 3-1/2 inch round replacement die?
Order model 2981AV. That is the manufacturer part number for the 3-1/2 inch round replacement die, and the same number is stamped on the die itself so you can match a worn one in hand against the box.
5) Can I use a round knockout die like this for a square or rectangular conduit opening?
No. This is a round die, so it only produces round knockouts for conduit and fitting entries. Rectangular openings for devices, meters or pilot-light cutouts need a square or rectangular punch and die of the matching size, not a round one.
6) What do the alignment markings on the Greenlee 2981AV die actually do for me?
The markings on the die face let you line the die up to a scribed centerline or layout mark on the enclosure before you draw the punch through, instead of eyeballing it. On a panel with a row of conduit entries that is what keeps the holes on a straight line and saves rework on a hole you cannot un-punch.
7) Is the Greenlee 2981AV die made in the USA for jobs with domestic sourcing requirements?
Country of origin is the United States, which is what institutional and government buyers working to a domestic-content clause need on record for electrical tooling purchases.
