Greenlee 7212SP-3/4D Conduit Round Punch Die 3/4 Inch

Product Description

The GREENLEE 7212SP-3/4D is a round conduit punch die designed for use with compatible Greenlee punch units to produce clean, accurate holes for 3/4 inch conduit installations. The die produces a hole diameter of 1.1155 inches (28.30 mm), sized to the standard knockout dimension required for 3/4 inch trade-size conduit. Electricians and electrical contractors use this die as part of a hydraulic or manual knockout punch set when working on enclosures, panels, junction boxes, and other sheet metal or similar substrates. It is sold as a single replacement or supplemental die component.

This die is suited for electrical trade applications where precise, burr-free knockouts are required for 3/4 inch conduit entries. Typical install scenarios include service panels, pull boxes, switchgear enclosures, and electrical distribution equipment in both residential and commercial work. The die is used in conjunction with a matching punch and punch unit — it does not function as a standalone tool.

Installation Notes

Installation of conduit knockout dies should be performed by a qualified electrician or electrical contractor in accordance with applicable NEC requirements. De-energize and lock out any enclosure or panel before punching to prevent contact with live conductors. Ensure the punch, die, and draw stud are properly aligned and seated in the punch unit before applying force. Inspect the die for wear or damage before each use and replace if threads or the cutting edge show signs of deterioration.
