Impact Socket Accessory Proline ZR18122, 75 mm length

Proline ZR18122 is an impact socket accessory with a 75 mm length, engineered for use with impact wrenches and pneumatic or electric impact drivers. It transfers torque from the tool to sockets and fasteners while enabling work in hard-to-reach places thanks to its compact extension design. The accessory includes a ball locking feature to secure sockets during operation and a rounded square pin that mates with impact tools, providing reliable engagement under heavy load.

Advantages

The 75 mm length adds reach without significantly increasing leverage that could affect control. The ball blocking mechanism holds sockets securely to prevent accidental disengagement during impact use. Constructed for impact applications, the extension resists the repeated high-torque shocks typical of pneumatic and electric impact drivers. One end features a square socket to accept standard impact sockets, while the other end has a rounded square pin for stable connection to the drive tool.

Suitable for

• Automotive repair and wheel or brake fastener work where extended reach is needed
• Machinery maintenance and service tasks in confined spaces
• Construction and assembly operations using impact wrenches or drivers
• General workshop applications requiring impact-rated socket extensions

Key specifications

• Type: impact socket extension/adapter
• Length: 75 mm
• Connection ends: square socket on one end, rounded square pin on the other
• Retention: ball locking mechanism to secure sockets
• Intended use: compatible with pneumatic and electric impact drivers

How to use

Select a compatible impact socket and push it onto the square socket end of the extension until the ball locking mechanism engages and holds the socket in place. Fit the rounded square pin into the drive of the impact wrench or driver and ensure a secure connection before applying torque. Use the accessory only with impact-rated sockets and tools, and avoid modifications; to remove the socket, depress or release the ball lock as designed and pull the socket off the extension.

Usage recommendations

Use the Proline impact extension with impact-rated sockets and appropriate drive-size tools. Wear eye and hand protection during impact tool use, and periodically inspect the extension for wear, deformation, or damaged retention ball. Replace the accessory if any signs of cracking, excessive wear, or rounding of connection surfaces are present to maintain safe and reliable operation.
