The WILLIAMS COMFORT PRODUCTS 31026 is a 3/8 inch drive locking extension bar with a 12 inch reach, built for trade professionals who need secure, positive-lock tool engagement during fastener work. The locking mechanism holds the socket in place on the drive, reducing drop risk in tight or overhead spaces. At 0.65 pounds, it is light enough for extended use without fatigue. This type of extension bar is a standard tool in HVAC, plumbing, and mechanical service kits where torque transfer and socket retention in confined spaces are routine requirements.
This extension bar fits standard 3/8 inch drive ratchets, torque wrenches, and breaker bars. It is suited for residential and light commercial service applications where techs are reaching fasteners behind panels, inside air handlers, around mechanical equipment, or in tight cabinet assemblies. The 12 inch length provides adequate reach for most confined-space fastener access without sacrificing control or torque feedback.
Designed for use with standard 3/8 inch drive ratchets, sockets, and torque wrenches commonly used in HVAC, plumbing, and mechanical service applications.
This extension bar is a hand tool requiring no installation. Ensure the socket is fully seated and the locking collar is engaged before applying torque. Inspect the drive tang and locking mechanism for wear before each use. Do not exceed the torque rating of the drive size to avoid tool failure or fastener damage.
