Extension bar KS Tools 911.1020 Chrome vanadium steel 200 mm

The KS Tools 911.1020 extension bar is a 200 mm chrome vanadium steel tool designed to increase reach and access in confined or recessed areas. It fits 1" drive sockets and offers a straight, single-piece construction that transfers torque from ratchets or breakers to sockets while maintaining alignment. The solid steel body and chrome finish provide resistance to wear and corrosion, delivering a practical accessory for workshop and maintenance tasks.

Advantages

This extension bar combines durable chrome vanadium steel construction with a corrosion-resistant chrome surface for long service life. Its 200 mm length gives added reach without excessive flex, and the standard 1" drive interface ensures compatibility with heavy-duty sockets and ratchets. The simple, robust design maintains torque transfer and alignment under load, making it suitable for repeated professional use.

Suitable for

• Automotive repair and underbody access where extra reach is required
• Industrial maintenance tasks using 1" drive sockets and ratchets
• Heavy-duty assembly or disassembly operations in workshops
• DIY projects that involve recessed or hard-to-reach fasteners

When it may not be suitable

This extension bar is intended for use with 1" drive tools; it is not compatible with smaller drive sizes without an adapter. It is a straight extension and does not provide swivel or universal joint functionality, so applications requiring angled access or flexible joints may need a universal adapter or jointed extension.

Key specifications

• Material: chrome vanadium steel
• Finish: chrome-plated surface for corrosion resistance
• Length: 200 mm
• Drive size: 1" (one inch)
• Design: straight, single-piece extension bar

How to use

Attach the extension bar to the square drive of a compatible ratchet, breaker bar or torque wrench until it seats securely. Fit the appropriate 1" drive socket onto the remote end, then apply torque using steady, controlled force. Use extensions to reach recessed fasteners while ensuring the connection is fully engaged to prevent slipping. After use, clean off debris and store the extension in a tool chest or holder to protect the finish.

What to consider before purchase

• Verify that your sockets and ratchet use a 1" drive to ensure compatibility
• Consider whether a 200 mm length provides the reach you need or if a shorter/longer extension is preferable
• Check that a straight extension meets your access requirements or if a swivel/universal joint is necessary

Usage recommendations

For reliable performance, use the extension bar only with hand tools rated for the intended torque and avoid sudden impact loads unless the tool is specified for such use. Keep the square drive and socket mating faces clean and lightly lubricated to ensure easy assembly and reduce wear.
