The WILLIAMS COMFORT PRODUCTS X-115 is a 1-inch drive extension measuring 16 inches in length, designed for heavy-duty fastening applications in the trades. Drive extensions of this type allow technicians to reach recessed fasteners and tight spaces where a standard socket wrench cannot access directly. This tool is suited for HVAC equipment installation, mechanical rooms, and other service environments where large-drive torque tools are required. It is typically used by licensed HVAC technicians, pipefitters, and millwrights working on commercial and industrial equipment.
The X-115 drive extension is well-suited for commercial HVAC installations, large mechanical equipment service, and industrial maintenance tasks that demand a 1-inch drive platform. Its 16-inch length provides the reach needed when working around ductwork, piping, or equipment panels that obstruct direct socket access. This extension is sold individually and fits into standard 1-inch drive tool sets used across the trades.
Designed as an OEM-style replacement and aftermarket addition compatible with standard 1-inch drive socket sets and torque wrenches used in commercial HVAC, mechanical, and industrial service applications.
This drive extension should be used by qualified tradespeople familiar with 1-inch drive tooling and appropriate torque practices. Ensure the extension is fully seated in both the drive tool and the socket before applying torque. Inspect the extension for cracks or deformation before each use. Follow applicable safety standards and equipment manufacturer torque specifications when tightening fasteners.
