Greenlee 745SP-1D Conduit Round Die 1 Inch Speed Punch

Product Description

The GREENLEE 745SP-1D is a round conduit die designed for use with Greenlee SPEED PUNCH System components. It produces a clean, precise knockout with a hole diameter of 1.36 inches, sized for 1-inch conduit. Electricians and maintenance technicians reach for this die when clean conduit knockouts are required in panel enclosures, junction boxes, and similar electrical enclosures. The die is a direct replacement or supplemental component within the SPEED PUNCH platform, keeping the system in production without requiring a full punch set replacement.

This die is suited for commercial and industrial electrical work where consistent, repeatable knockout quality is essential.

Installation Notes

Installation of conduit dies should be performed by a qualified electrician in accordance with NEC requirements. Always de-energize and lock out any panel or enclosure before beginning knockout work. Ensure the die is properly seated and aligned with the corresponding punch before applying hydraulic or mechanical force. Inspect the die for wear or damage before each use to maintain clean, burr-free knockouts.
