The GREENLEE 13276 is a punch adapter unit designed for 1/2-inch conduit knockout work. It serves as a replacement or supplemental adapter component within Greenlee's knockout punch system, allowing electricians and conduit installers to complete precise, clean holes in enclosures, panels, and junction boxes. The adapter interfaces with the punch and die assembly to maintain proper alignment and drive force during the knockout process. At approximately 7.24 inches by 5.00 inches by 0.12 inches, this is a low-profile component built for job site use by licensed electricians and electrical contractors.
This adapter unit is suited for electrical trade applications where 1/2-inch conduit entries are required. Typical use cases include panel installations, enclosure fabrication, and conduit rough-in work in residential, commercial, and light industrial settings. The 13276 is a single-pack unit, making it a practical replacement or spare for an existing Greenlee knockout punch set. It is intended for use as part of a complete punch and die assembly, not as a standalone punching tool.
Designed as an OEM-style adapter component for use with Greenlee knockout punch sets configured for 1/2-inch conduit applications.
Installation and replacement of punch adapter components should be performed by a qualified electrician. De-energize all circuits and follow lockout/tagout procedures before working inside panels or enclosures. Verify that the adapter is fully seated and aligned within the punch assembly before applying drive force. Consult the tool manufacturer's instructions for the complete punch system setup and safe operating procedures.
