UNI Chain Drive Extension Wrench 1/4" – 3/8" Drive

The UNI chain-driven extension wrench was specially developed for working on hard-to-reach fasteners. With its length of 340 mm and particularly slim profile, it allows access to screws and nuts in confined engine compartments, machines or hard-to-reach assemblies, where conventional tools reach their limits.

The extended drive rod and robust chain drive reliably transmit power to the fastening point and ensure maximum flexibility for maintenance and repair work. Thanks to the included adapters, the tool is compatible with various drive sizes and can be used in a variety of ways.

Ideal for working on water pumps, power steering pumps, generators, air conditioning compressors, transmissions, starters and many other components.
