Greenlee K3P-2 Round Knockout Punch Die 2 Inch Conduit

Product Description

The GREENLEE K3P-2 is a round knockout punch die designed for cutting clean, precise holes in electrical enclosures, panel boxes, and sheet metal. It produces a 2.42-inch diameter hole sized to accept 2-inch conduit fittings. The punch is used as part of a knockout punch set — paired with a draw stud, die, and hydraulic or manual driver — to remove a slug of material without drilling or cutting by hand. Electricians and panel installers rely on this type of punch die for fast, burr-free knockouts in both field and shop work. The unit ships individually and weighs 1.3 pounds.

This punch die is suited for residential and commercial electrical work where conduit entries must be added to enclosures, junction boxes, meter bases, or load centers. It is sized specifically for 2-inch trade-size conduit, making it a common choice on larger commercial conduit runs where EMT, rigid, or IMC at 2-inch diameter terminates at a panel or enclosure. The round profile is the standard geometry for conduit knockouts.

Installation Notes

Knockout punch dies are installed by licensed electricians in accordance with NFPA 70 (NEC) requirements for conduit entry and enclosure work. De-energize and lock out all panels or enclosures before beginning any knockout operation. Ensure the correct die is paired with the matching draw stud and that the workpiece material thickness is within the rated capacity of the punch driver being used. Inspect the punch edge for wear or chipping before each use to ensure a clean, burr-free cut.
