Greenlee 51040110 – Frequently Asked Questions
1) What size hole does the Greenlee 51040110 die actually cut?
The 51040110 is sized for 1 inch conduit, and the actual hole it produces is 1.362 inches in diameter. That is the standard clearance hole for a 1 inch conduit hub or connector, so the fitting drops in without reaming.
2) Is the Greenlee 51040110 a complete knockout punch or just the die?
Die only. The 51040110 is a replacement die for 1 inch conduit size, so you still need the matching punch and a draw stud or bolt to pull it. If your existing 1 inch punch is still good, this replaces the worn die half only.
3) Will the Greenlee 51040110 die work with my standard round knockout punch set?
Yes, it is made for standard round knockout punches in the 1 inch conduit size. It is a round die, not a square or D-shaped one, so it pairs with the round punch of the same size. Match the draw stud thread on your existing set before ordering.
4) What part number do I order to replace a worn 1 inch Greenlee round knockout die?
Greenlee 51040110 is the part number for the 1 inch conduit size round replacement die. It is made in the US. Order by that number rather than by hole size alone, since 1 inch conduit and a 1 inch hole are two different things here.
5) Can I use the 1 inch conduit die to punch a hole for something other than conduit?
Any fitting or device needing a 1.362 inch round hole works, since that is the finished hole size the die cuts. Cord grips, cable glands, and pilot lights specified at 1 inch trade size all land on that same opening.
6) How big is the Greenlee 51040110 die, and will it fit my punch case?
The die measures 3.750 x 3.750 x 3.750 inches as packed. That is the shipping envelope, useful if you are slotting it into a punch kit case or a truck drawer.
