The KLEIN TOOLS 50400 is a 12-inch hand cable bender designed for forming and routing large-diameter electrical cables in the field. Built for licensed electricians working with heavy conductors, this tool handles cable up to 300 MCM, making it suitable for service entrance work, feeder runs, and panel connections where tight, clean bends are required without damaging the conductor insulation. At 0.94 pounds, it is light enough for one-handed use while maintaining the leverage needed to work stiff, large-gauge cable. This is a hand-operated tool requiring no hydraulic or mechanical assist.
The 50400 is used in residential and commercial electrical installations where large-gauge conductors must be bent to fit conduit entries, panel knockouts, and equipment terminations. It is particularly suited to service work involving 300 MCM aluminum or copper feeder cable. Electricians will find it useful during new construction rough-in, service upgrades, and industrial panel builds where controlled, repeatable bends on heavy cable are necessary.
Designed for use with electrical cable up to 300 MCM in standard residential and commercial electrical installations. No specific compatible model numbers or replacement part numbers were provided in the product data.
This tool is used by licensed electricians and should be operated in accordance with NEC guidelines for conductor handling and termination. Always de-energize the circuit and follow lockout/tagout procedures before working near existing conductors. Inspect the tool for cracks or deformation before each use, and do not exceed the rated 300 MCM cable capacity, as overloading can damage both the tool and the conductor jacket.
