Purpline Nemesis Ultra wheel clamp high security

Weighing in at just over 3kg and able to fit in a shoe box, installation of the Nemesis Ultra wheel clamp is a simple matter of locate, lock and go. Despite its compact size it is incredibly secure, boasting SCM European Quality Assured status.
The unique feature of the patented design Nemesis Ultra is that the clamp locks to a universal wheel bolt and the clamp itself goes through the wheel as opposed to around it as with a traditional wheel clamp, meaning that all the parts that would need to be attacked in an attempt to remove the clamp are either in or behind the wheel, making access incredibly difficult for the would-be thief.
