Proto J6222 Torque Wrench Multiplier 2200 Ft-lb

Product Description

The PROTO J6222 is a two-stage torque wrench multiplier designed for high-torque fastening applications where standard torque wrenches cannot reach the required output. It delivers a maximum output of 2,200 ft-lb through a 1-inch output drive, using a 15:1 gear ratio and an effective multiplier ratio of 1:13.6. This tool is built for industrial and heavy-duty trade environments where controlled, repeatable torque is critical. Millwrights, maintenance mechanics, and industrial service technicians use multipliers like the J6222 when working on large flanged connections, structural bolting, and heavy equipment assembly.

The J6222 is suited for applications requiring high-torque output in confined or production settings where pneumatic or hydraulic tooling is not available or practical. Its two-stage gear system allows a standard torque wrench to serve as the input driver, amplifying output force to reach fastener specifications that would otherwise require specialized power tooling. Typical use cases include pipeline flanges, turbine covers, large pump assemblies, and structural steel connections in commercial and industrial settings.

Key Features

• 2,200 ft-lb maximum output torque for heavy industrial fastening
• 1-inch output drive accommodates large drive sockets
• Two-stage gear system with a 15:1 gear ratio
• Effective multiplier ratio of 1:13.6 allows use with a standard torque wrench as input
• Compact multiplier design suitable for confined-space bolting applications

Compatibility

Designed for use with standard torque wrenches as an input driver, compatible with 1-inch drive sockets and fastener tooling rated for high-torque industrial applications.

Installation Notes

The J6222 should be operated by a qualified mechanic or industrial maintenance technician familiar with torque multiplier procedures. Always verify the reaction arm is properly braced against a fixed surface before applying input torque to prevent tool movement or injury. Confirm the input torque wrench is calibrated and rated for use with a multiplier. Follow applicable torque specifications from the equipment manufacturer or relevant industry standards when determining final output torque targets.
