Cleco 55RNL-4T-4 Pneumatic Stall Collar Reverse Angle Nutrunner | 55 Series | Lever Start | 290 RPM | 68 (ft-lbs) Max Torque

Built for production fastening where access is limited and controlled torque is required, the Cleco 55RNL-4T-4 Pneumatic Stall Collar Reverse Angle Nutrunner combines a compact right-angle configuration with 290 RPM free speed and 68 ft-lbs maximum torque. The 55 Series tool uses a stall-type fastening system (the motor stops as joint resistance reaches the tool's torque capability), giving assembly operators direct control over final tightening without an impact mechanism. Its lever start control supports deliberate tool activation, while the reverse angle head helps operators reach fasteners positioned near fixtures, machine frames, and other obstructions.

The Cleco 55RNL-4T-4 is suited to repeated nut and bolt tightening in manufacturing, equipment assembly, and industrial production environments. Its 290 RPM speed favors controlled rundown of larger threaded fasteners, while the 68 ft-lbs maximum torque capacity supports higher-torque fastening tasks within the tool's specified operating range. The reverse capability also allows operators to back out fasteners during assembly adjustments, rework, and service operations.

Type: Pneumatic Stall Collar Reverse Angle Nutrunner | Model: 55RNL-4T-4 | Series: 55 Series | Start Type: Lever Start | Free Speed: 290 RPM | Max Torque: 68 ft-lbs

Features:

• Stall-type fastening operation provides direct tightening control as the motor stalls against increasing joint resistance.
• Reverse angle configuration provides access to fasteners positioned near fixtures, machine structures, and other assembly obstructions.
• 290 RPM free speed supports controlled fastener rundown in higher-torque assembly operations.
• 68 ft-lbs maximum torque capacity accommodates industrial nut and bolt tightening tasks within the tool's specified torque capability.
• Lever start control allows deliberate activation during repetitive production fastening.
• Reversible operation supports fastener removal, assembly adjustments, and production rework.
• 55 Series pneumatic platform is intended for industrial assembly and production fastening applications.

Made in USA:

Applications:

• Industrial production assembly — tightening nuts and bolts where controlled rundown and stall-type fastening are specified.
• Machinery and equipment manufacturing — reaching fasteners located around frames, fixtures, brackets, and structural components.
• Vehicle and component assembly — repetitive pneumatic fastening operations that require a reversible right-angle tool.
• Plant assembly stations — installing and removing threaded fasteners during production, adjustment, and rework processes.
• General manufacturing — higher-torque fastening tasks that fall within the tool's 68 ft-lbs maximum torque capability.

FAQs:

• Q: What type of nutrunner is the Cleco 55RNL-4T-4?
  A: The 55RNL-4T-4 is a pneumatic stall collar reverse angle nutrunner. A stall tool tightens the fastener until increasing joint resistance causes the air motor to stop, allowing the operator to control the fastening cycle without an impact mechanism.
• Q: What is the maximum torque of the Cleco 55RNL-4T-4?
  A: The tool has a maximum torque rating of 68 ft-lbs. Fastening applications should be evaluated against the manufacturer's specified operating range and the torque requirements of the joint.
• Q: Why use a reverse angle nutrunner instead of a straight pneumatic tool?
  A: The angle configuration helps reach fasteners positioned close to fixtures, frames, machinery, and other obstructions. Reverse operation also allows the tool to remove fasteners during adjustment, rework, and service tasks.
• Q: Is the 55RNL-4T-4 suitable for repetitive production fastening?
  A: Yes. Its pneumatic operation, lever start control, 290 RPM free speed, and angle configuration support repeated fastening tasks in industrial assembly environments when the joint requirements match the tool's torque capability.
