Williams Comfort Products B-118 Drive Extension

Product Description

The WILLIAMS COMFORT PRODUCTS B-118 is a 3/8-inch drive extension bar measuring 18 inches in length, designed for use with 3/8-inch drive ratchets and socket sets. This extension provides added reach in confined or deep-access work areas where a standard-length drive setup cannot make contact with the fastener. It is a hand tool commonly used by HVAC technicians, plumbers, electricians, and other trade professionals during equipment installation and service work. At 0.93 pounds, it is lightweight enough for extended single-hand use without added fatigue.

This extension is suited for residential and commercial service applications where fasteners are recessed, deeply mounted, or positioned in tight enclosures. Typical use cases include equipment panel fasteners, motor mount bolts, and access-restricted hardware found in HVAC air handlers, furnaces, water heaters, and electrical panels. It pairs with any standard 3/8-inch drive ratchet, breaker bar, or torque wrench and compatible 3/8-inch drive sockets.

Installation Notes

This tool is used by licensed tradespeople across HVAC, plumbing, and electrical service disciplines. Ensure the extension is fully seated into the drive tool and socket before applying torque to prevent slippage or fastener damage. Do not use extension bars with impact drivers unless the extension is rated for impact use. Inspect the drive square and detent mechanism for wear before use on critical fasteners.
