Cleco 55RNAL-4P-4 Clutch Shut-Off Pneumatic Angle Nutrunner | Collar Reverse | Lever Start | 55 Series | 330 RPM | 26 - 54 (ft-lbs) Torque Range

When you need precise torque control in assembly or maintenance tasks, the Cleco 55RNAL-4P-4 delivers a 26–54 ft-lbs torque range (suitable for small-to-medium fasteners with consistent tightening), a 330 RPM free speed for efficient rundown, and a shut-off clutch mechanism that automatically stops the tool when the preset torque is reached (ensuring accurate fastening and preventing over-tightening). Its angle head design allows access to confined spaces and awkward angles, while the collar reverse and lever start controls provide intuitive operation in repetitive assembly settings. Engineered for production assembly, automotive, and light industrial maintenance, this tool is built to keep workflow steady while reducing operator fatigue and ensuring repeatable results across every joint.
