The KLEIN TOOLS 53838 is a knockout die sized for 1-inch conduit, producing a 1.362-inch knockout opening in electrical enclosures, panels, and junction boxes. The die is used with a compatible knockout punch driver to create clean, precise holes in sheet metal without drilling or cutting. It is a standard component in conduit entry work performed by licensed electricians and electrical contractors. The compact die measures 3.7 inches long by 3.4 inches wide by 2.4 inches tall and weighs 0.35 pounds, making it easy to handle in tight cabinet spaces.
This knockout die is intended for electrical rough-in and panel work where 1-inch conduit entries are required. It is commonly used when installing EMT, rigid metal conduit, or IMC into enclosures, load centers, and pull boxes. The 1.362-inch knockout diameter conforms to standard trade-size specifications for 1-inch conduit knockouts, allowing fittings to seat and thread properly without modification.
Designed as an OEM-style replacement or supplemental die for use with Klein knockout punch sets that accept standard conduit knockout dies sized for 1-inch trade-size conduit applications.
This die is installed by a licensed electrician working with a knockout punch driver assembly. De-energize all equipment before making conduit entries in live panels or enclosures, in accordance with NFPA 70 lockout/tagout requirements. Align the die and punch squarely against the work surface to ensure a clean, round knockout. Inspect the die for wear or damage before each use and do not exceed the rated capacity of the punch driver being used.
