Cleco 55RNAL-3P-4 Clutch Shut-Off Pneumatic Angle Nutrunner | Collar Reverse | Lever Start | 55 Series | 220 RPM | 36 - 80 (ft-lbs) Torque Range

When you need precise torque control in assembly or maintenance tasks, the Cleco 55RNAL-3P-4 delivers a 36–80 ft-lbs torque range (suitable for medium-fastening tasks requiring accurate repeatable tightening), a 220 RPM free speed for efficient run-down, and a shut-off clutch mechanism that automatically stops the tool when the preset torque is reached (preventing over-tightening and ensuring consistent results). Its angle head design allows access in confined spaces, while the collar reverse and lever start controls provide intuitive operation for repetitive assembly. Ideal for production assembly, automotive, and light industrial maintenance, this tool helps maintain consistent fastening quality while reducing operator fatigue.
