The WILLIAMS COMFORT PRODUCTS QJBOER18A is a 12-point ratchet head designed for use with CDI torque tools. This ratchet head accepts 9/16 inch fastener sizes and is built for professional torque applications where precise fastener engagement is required. The 12-point geometry allows for a wider range of handle positions in confined work areas, making it practical for technicians working in tight spaces on mechanical systems. Sold individually, this ratchet head is intended for trade professionals who require reliable, interchangeable tooling components.
This ratchet head is suited for use in mechanical, HVAC, plumbing, and electrical service environments where CDI-compatible torque ratchet systems are already in use. It is appropriate for both residential and light commercial service work where 9/16 inch fasteners are encountered during installation or maintenance tasks. The unit-each packaging makes it a practical replacement or addition to an existing CDI tool set.
Designed for use with CDI torque ratchet systems accepting 9/16 inch 12-point ratchet heads. Verify fitment with your specific CDI torque tool model before installation.
Installation of this ratchet head should be performed by a qualified technician familiar with CDI torque tool systems. Ensure the torque tool is not under load before attaching or removing ratchet heads. Confirm the head is fully seated and locked before applying torque to any fastener. Follow the tool manufacturer's guidelines for proper attachment and torque application procedures.
