Cleco 55RNL-7T-4 Nut Runner 41 Ft/lb 1/2 Inch Drive

Product Description

The CLECO 55RNL-7T-4 is a pneumatic nut runner designed for production assembly and fastening applications requiring precise torque output. Driven by compressed air, this tool delivers 41 ft/lb (492 in/lb, 56 N/m) of torque through a 1/2 inch square drive at up to 490 RPM. It operates on a 1/2 NPT inlet and consumes 55 SCFM of air at rated load. The tool is well-suited for industrial assembly lines, maintenance facilities, and heavy trade environments where repeatable fastening torque is critical. Licensed professionals and production technicians in manufacturing and mechanical trades are the primary installers and operators of this class of tool.

The 55RNL-7T-4 is intended for use in assembly and production settings where consistent nut running and fastening performance is required. Its 1/2 inch drive accepts standard impact sockets, making it compatible with a wide range of fastener sizes commonly encountered in structural, mechanical, and equipment assembly work. The 1/2 NPT air inlet fits standard shop air line fittings found in most production and service environments.

Compatibility

Designed as a production-grade pneumatic nut runner compatible with standard 1/2 NPT shop air supply systems and 1/2 inch drive impact socket sets used in industrial assembly and mechanical service applications.

Installation Notes

This tool is installed and operated by qualified assembly technicians or mechanical trade professionals working with compressed air systems. Before connecting to the air supply, verify that the line pressure matches the tool's rated operating requirements and that an inline lubricator and filter-regulator are installed per standard pneumatic tool practice. Never exceed the rated torque or RPM by over-pressurizing the air supply. Ensure the air line is depressurized before connecting or disconnecting fittings.
