Williams Comfort Products B-108 Drive Extension

Product Description

The WILLIAMS COMFORT PRODUCTS B-108 is a 3/8 inch drive extension measuring 3 inches in length, designed for use with standard 3/8 inch drive ratchets and sockets. This type of hand tool extension is commonly used by HVAC technicians, plumbers, electricians, and general trade professionals who need added reach when driving fasteners in confined or hard-to-access spaces. The B-108 provides a rigid, reliable connection between the drive handle and socket, making it a straightforward addition to any trade tool set.

This drive extension is suited for a wide range of service and installation tasks across HVAC, plumbing, electrical, and mechanical trades. Its compact 3 inch length makes it particularly useful in tight equipment cabinets, panels, and access areas where a standard ratchet alone cannot reach the fastener. It is sold individually and is appropriate for both residential and light commercial service work.

Key Features

• 3/8 inch drive size compatible with standard 3/8 inch drive sockets and ratchets
• 3 inch extension length for added reach in confined spaces
• Lightweight at 0.188 pounds for easy handling during service calls
• Sold as a single unit for targeted replacement or kit addition

Compatibility

Designed as a standard 3/8 inch drive extension compatible with 3/8 inch drive ratchets and sockets from most major tool manufacturers.

Installation Notes

This extension is a hand tool and does not require installation in the traditional sense. Ensure the drive connection is fully seated before applying torque to avoid slippage or rounding of fasteners. Use appropriate personal protective equipment when working in energized panels or pressurized systems, and follow all applicable trade codes and safety procedures for the task at hand.
