Greenlee 745SP-3/4P Conduit Round Punch 3/4 Inch

Product Description

The GREENLEE 745SP-3/4P is a round conduit punch designed for use with the Greenlee SPEED PUNCH system. It punches a 1.11-inch diameter hole sized for 3/4-inch conduit. This punch is a replacement component, meaning it is purchased separately to replenish or expand an existing SPEED PUNCH setup rather than as part of a complete kit. Electricians and electrical contractors use this punch when knockout work is required on enclosures, panels, and electrical boxes. The precise hole geometry ensures clean, burr-free knockouts that meet conduit fitting requirements.

This punch is intended for use with compatible Greenlee SPEED PUNCH system components. It is suited for residential and commercial electrical work where 3/4-inch conduit knockouts are needed in sheet metal enclosures, junction boxes, and load centers. The replacement-only design makes it a practical spare to keep on hand when punch components wear or when a specific conduit size needs to be added to an existing set.

Installation Notes

Installation of conduit punches is typically performed by licensed electricians. Before punching, de-energize all equipment in or near the enclosure being worked on and follow applicable NEC guidelines for working on electrical enclosures. Ensure the punch, draw stud, and die are properly aligned before applying hydraulic or manual force to avoid damaging the punch or workpiece. Inspect the punch for wear or cracking before each use and replace immediately if damage is found.
