Extension Bar 1/2" 125 mm Proxxon PR23454

Proxxon 1/2" 125 mm extension bar PR23454 is a solid metal extension designed to increase the reach of 1/2-inch drive sockets. The extension provides reliable connection between sockets and 1/2" ratchets or torque tools, enabling access to fasteners located in recessed, narrow, or otherwise hard-to-reach areas. Its 125 mm length offers additional clearance while maintaining control and torque transfer for standard mechanical and maintenance tasks.

Advantages

The extension bar is manufactured from hardened steel for strength and wear resistance, with a precise square drive to ensure secure socket retention and minimal play. Its polished finish reduces corrosion and allows smooth insertion and removal of sockets. The 1/2" drive size is compatible with a wide range of professional and consumer sockets and tools, making it a versatile addition to workshop toolkits.

Suitable for

• Automotive repair and servicing where fasteners sit deep within engine bays or suspension assemblies
• Mechanical assembly and disassembly tasks requiring extra reach
• Maintenance work in industrial or household equipment with recessed bolts and nuts

Key specifications

• Drive size: 1/2 inch
• Length: 125 mm
• Material: hardened steel
• Finish: polished corrosion-resistant surface

How to use

Select a compatible 1/2" socket and push it onto the extension bar's square drive until it engages. Attach the extension to a 1/2" ratchet or torque tool, then fit the socket to the fastener. Apply torque in controlled increments appropriate to the fastener and application, keeping the extension aligned to avoid side loading. After use, clean any contaminants from the extension and lightly oil if necessary to prevent corrosion.

Usage recommendations

The extension bar is intended for use with compatible 1/2" sockets and drive tools; avoid using it as a lever or breaker bar beyond rated torque limits. Inspect the square drive and socket retention surfaces regularly for wear, and replace the extension if deformation or excessive wear is detected to maintain safe operation.
