Greenlee 7804SB Hydraulic Punch Driver Kit 5 Piece

Product Description

The GREENLEE 7804SB is a 5-piece hydraulic punch driver kit designed for punching clean, round holes in mild steel panels, enclosures, and electrical boxes. The kit operates hydraulically, reducing the hand force required compared to manual knockout sets. It handles mild steel up to 10 gauge and produces a 22.5-inch hole diameter, making it suited for larger conduit or fitting entries in sheet metal work. Licensed electricians and electrical contractors are the primary users of this kit, typically during panel installation, enclosure fabrication, or conduit-entry work on commercial and industrial jobs.

This kit is built for electrical trade applications where consistent, burr-minimized round knockouts are needed in steel enclosures and junction boxes. The 22.5-inch punch hole diameter accommodates large conduit entries. The hydraulic operating method allows one technician to drive the punch without excessive effort, which is practical in tight spaces or overhead installations. The included plastic carrying case keeps all components organized on the job site.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lock out all circuits in the enclosure before beginning any punch work. Ensure the draw stud is properly centered and seated before applying hydraulic pressure to avoid damaging the punch or die. Inspect all components for wear or damage before each use.
