Chicago Pneumatic C-051536 Spline Torque Bar Extension is a Type E spline-drive extension bar in CP's Tork Bar Kit family, identified in CP's spline-bar catalog as size #6, and designed to engage with Chicago Pneumatic spline-drive torque tools to extend reach for high-torque fasteners. The extension uses a 'C' spline interface to provide positive engagement under heavy loads and to transfer torque efficiently when fasteners are recessed or in tight spaces. It is intended for use with CP torque tools that support spline-drive bars, enabling torque transfer in challenging assembly scenarios while remaining compatible with CP's spline-bar ecosystem.
