Insulated 125 mm Extension Bar

This Knipex 98-35-125 extension bar provides a 125 mm reach with a 3/8 inch square drive on both ends. The male output and female input allow direct attachment to 3/8 inch drive sockets and ratchets. It is manufactured from alloy steel with a chrome finish and features insulated construction for electrical work.

Electricians needing insulated reach

The insulated design suits electricians and technicians who require a 3/8 inch drive extension for tasks where electrical insulation is a safety requirement. Builders who need a different drive size such as 1/4 inch or 1/2 inch, or a non-insulated extension for general mechanical work, should look at other options.

3/8 inch square drive compatibility

The single specification that decides fit is the 3/8 inch square drive on both input and output. This extension only works with 3/8 inch drive sockets, ratchets and accessories; it will not connect to 1/4 inch or 1/2 inch drive tools.
