Britool England 3/8" Drive Lock-On Extension Bar Range

These 3/8-inch square drive extension bars feature an integrated quick-release lock-on mechanism. The mechanism retains attached sockets onto the drive end until manually released, preventing sockets from separating inside deep engine bays or tight assemblies.

The range includes lengths of 50mm, 90mm, and 340mm to provide clear access past surrounding components. The 90mm and 340mm versions carry standard brand markings, while the compact 50mm option remains unstamped due to its reduced body length.

Developed as part of the Hallmark automotive tool series, these bars carry the standard Britool Hallmark guarantee covering material defects and manufacturing faults.
