Supplied by Simplicity but sold under the Unipart Route 2000 brand. They have been in our stores a while so the boxes are tatty and the clamps slightly shop soiled.

These are designed more for when the caravan or trailer is in storage as it involves removing two of the wheel bolts or nuts and using them to fix the clamp.  The locking pin is then fitted preventing the removal of the wheel.  They are a good effective security device and have been copied by other manufacturers since originally designed.

There are three with 100mm PCD (common on caravans) and one with 5.5" PCD (common on braked trailers)

The price is for all four and is effectively four for the original price of one.  We are moving to smaller premises and need to reduce our stock

One of the 100mm does not have its original box.
