Extension Bar EPM 1/2" 125 mm model E-400-0901

The EPM Extension Bar 1/2" 125 mm (model E-400-0901) is a rigid hand tool accessory designed to extend the reach of 1/2-inch drive sockets and ratchets. With a 125 mm length, this extension bar allows access to recessed fasteners and confined spaces that are difficult to reach with standard socket handles. It is intended for use with compatible 1/2" drive tools in automotive, mechanical and maintenance environments to improve reach and transfer torque reliably.

Advantages

This extension bar provides a straightforward solution for accessing bolts and nuts located in tight or recessed positions without altering the applied torque significantly. Its compact 125 mm length balances reach and control, reducing the need for improvised extensions. Constructed to mate securely with 1/2" drive sockets and ratchets, it supports efficient transfer of turning force and maintains socket alignment during use.

Suitable for

• Automotive repair and servicing where fasteners are recessed
• Mechanical assembly and disassembly in workshops
• Maintenance tasks in confined or hard-to-reach areas
• General use with 1/2" drive socket sets and ratchets

Key specifications

• Drive size: 1/2 inch
• Overall length: 125 mm
• Function: extension for sockets and ratchets
• Compatibility: for use with 1/2" drive socket tools
• Typical applications: automotive, mechanical, maintenance

How to use

Attach the extension bar to the square drive of a compatible 1/2" ratchet or breaker bar by aligning the detent or recess and pressing until it seats securely. Connect the desired 1/2" socket to the opposite end, ensuring a firm connection before applying torque. Use the combined tool to reach recessed fasteners; apply steady, controlled force and avoid sudden impacts unless the tools are rated for impact use.

Usage recommendations

Inspect connections before each use to confirm the extension and socket are fully engaged. For high-torque applications, use tools rated for the intended loads and avoid excessive bending force. Store the extension bar with the rest of the socket set to prevent corrosion and damage.
