Brass battery terminal clamp to fit the negative post that allows the battery to be quickly isolated by unscrewing the green dial. This acts as a simple security device, ensuring that the vehicle cannot be started.

Comes complete with a pre-terminated fuse holder and 5A fuse to supply permanently powered low current circuits such as central locking, alarm, radio, clock etc. In the event of an attempt to start the engine the large current draw will blow the fuse and leave the battery completely isolated. The fuse holder should be fitted so that it bridges the dial.

Once fitted to your battery terminal, simply tighten your existing negative battery clamp to the end.

Fits SAE tapered lead negative battery posts.

Sold individually.

  • Material: Brass-plated zinc

Surprisingly useful
24 August 2020  | 

When I bought this isolation clamp I had no great expectations for it other than saving the battery while the car was not in use. However I've found it incredibly useful while working on the electrics of the car as I can easily connect and disconnect the battery thereby resisting he temptation to cut corners and work with the battery connected.
