Williams Comfort Products M-104 1/4 in Drive Extension

Product Description

The WILLIAMS COMFORT PRODUCTS M-104 is a 1/4 inch drive extension measuring 4 inches in length, designed for use with 1/4 inch drive ratchets and socket sets. This extension adds reach in tight or recessed fastener locations where a standard socket and ratchet cannot fit directly. It is a hand tool staple for HVAC technicians, plumbers, electricians, and other trade professionals who regularly work in confined equipment spaces. At 0.11 pounds, the M-104 is lightweight and easy to maneuver in cramped installations.

This extension is suited for general trade and service work across residential and commercial applications. It fits into equipment cabinets, electrical panels, junction boxes, and mechanical rooms where fastener access is restricted. HVAC techs use extensions like this when securing blower compartment hardware, panel fasteners, and equipment mounting bolts that are recessed beyond the direct reach of a ratchet head.

Key Features

• 1/4 inch drive compatibility works with standard 1/4 inch drive sockets and ratchets
• 4 inch length adds reach in recessed or tight fastener locations
• Lightweight at 0.11 pounds for easy single-hand use
• Compact form factor suited for confined equipment spaces

Compatibility

Designed as a standard 1/4 inch drive accessory compatible with 1/4 inch drive socket sets and ratchets from major tool manufacturers.

Installation Notes

This extension is a hand tool and requires no power source or special installation procedure. Ensure the drive end is fully seated into the ratchet and the socket is fully seated onto the extension before applying torque. Inspect the extension for cracks or deformation before use, and do not use a cheater bar or additional leverage on a 1/4 inch drive extension, as this can cause failure.
