Greenlee 234 Punch Unit 37 Pin

Product Description

The GREENLEE 234 is a 37-pin punch unit designed for creating clean, precise knockout holes in electrical enclosures, panels, and junction boxes. It delivers the driving force needed to punch through metal without distorting the surrounding material, making it a reliable choice for electricians working on conduit entry points and connector pass-throughs. The 234 is built for trade use in panel fabrication and enclosure prep work, where hole quality and consistency matter for proper connector seating and code-compliant installations.

The GREENLEE 234 is suited for commercial and industrial electrical work where 37-pin connector cutouts are required in steel or similar enclosure materials. It is typically used by licensed electricians and panel builders during rough-in and enclosure modification tasks. The punch unit integrates into standard knockout punch workflows, pairing with appropriate draw studs and hydraulic or manual drivers as part of a complete punching system.

Key Features

• 37-pin punch configuration for connector-specific knockout applications
• Designed for clean, burr-minimizing cuts in metal enclosures
• Compatible with standard GREENLEE knockout punch driver systems
• Supports accurate, repeatable hole placement for multi-pin connector installations

Compatibility

Designed as an OEM-style replacement or direct-use punch unit for 37-pin connector knockout applications in standard electrical enclosure punch sets.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC guidelines. Always de-energize and lock out the enclosure or panel before beginning any knockout or punch work. Use the correct draw stud size and ensure the punch and die are properly aligned before applying force to avoid damaging the tooling or workpiece. Inspect the punch unit for wear or cracking before each use.
