The PROTO J6222CERT is a two-stage torque wrench multiplier designed for high-torque fastening applications where standard hand tools cannot achieve the required output. It accepts a 1-inch square drive and delivers a maximum output torque of 2,200 ft-lb through a 13.6:1 gear ratio, with an effective multiplier ratio of 1:13.7. The unit weighs 20.44 pounds and features a head thickness of 5.75 inches and a head diameter of 4.06 inches. This tool is used by industrial maintenance technicians, heavy equipment mechanics, and millwrights who need precise, repeatable high-torque output without impact tools.
The J6222CERT is suited for heavy industrial and commercial maintenance environments where large-diameter fasteners require controlled torque application. Typical applications include bolted flange assemblies, structural steel connections, heavy machinery mounting hardware, and pipeline flanges. The two-stage gear system allows the operator to apply significant output torque using a standard torque wrench as the input tool, making it practical for confined or overhead installations where impact wrenches are not appropriate or code-compliant.
Designed as an OEM-style replacement and direct-use torque multiplier compatible with standard 1-inch square drive torque wrenches used as input tools in industrial fastening applications.
Installation and operation should be performed by qualified industrial mechanics or maintenance technicians familiar with torque multiplier equipment. Before use, ensure all reaction arm contact points are properly secured against a fixed surface to prevent rotation under load. Verify the input torque wrench calibration before calculating output torque using the gear ratio. Do not exceed the rated maximum output torque of 2,200 ft-lb, as overloading can damage the gear system or fastener assembly.
