Extension Bar 3/8" 150 mm Proxxon PR23556

Proxxon extension bar 3/8" 150 mm PR23556 is a compact hand tool accessory that increases reach for 3/8-inch drive sockets. The 150 mm length allows access to recessed or hard-to-reach fasteners while maintaining reliable torque transfer between the ratchet and the socket. Designed for use with compatible 3/8" drive ratchets and sockets, this extension bar is intended for tasks that require extended reach without sacrificing control.

Advantages

The extension bar offers a straightforward design that preserves torque transmission and socket engagement. Its 150 mm length balances reach and control, enabling work in narrow or recessed areas. Constructed for mechanical and maintenance use, the tool is compatible with standard 3/8" drive accessories and provides a stable connection between ratchet and socket for consistent performance.

Suitable for

• Automotive repair and maintenance where bolts or nuts are recessed
• Mechanical and equipment servicing in tight assemblies
• General workshop tasks requiring additional socket reach
• Maintenance of appliances and industrial machinery with limited access

Key specifications

• Drive size: 3/8 inch
• Overall length: 150 mm
• Function: extends reach between ratchet and socket
• Material: hardened steel suitable for torque transmission
• Connection type: square drive at both ends for ratchet and socket compatibility

How to use

Select a compatible 3/8" drive ratchet and socket, then push the socket onto the extension bar's square drive until it clicks or seats securely. Attach the extension bar to the ratchet in the same way. Apply torque through the ratchet as required, taking care to maintain alignment between tool components. Remove the extension by pressing the socket retention mechanism (if present) or by pulling the socket off the square drive when work is complete.

Usage recommendations

Use the extension bar only with sockets and ratchets of matching 3/8" drive size. Avoid applying impacts with power tools unless the extension is specifically rated for impact use. Inspect the mating surfaces before use to ensure secure engagement and replace the extension if signs of wear or deformation appear.
