A security device for vehicles, caravans and trailers (including small plant) to immobilise them to prevent theft comprises a hub plate which is filled to the hub with security wheel nuts or studs after a wheel is removed, the hub plate having tubes welded to it to prevent access to the nuts or studs. A base is bolted to the hub plate with a series of holes to enable adjustment in the effective height to compensate for uneven ground and to allow side to side levelling. A cover is then slid over the hub plate and secured with a padlock, the cover encasing the padlock to prevent forced removal. The device is manufactured from plate steel, welded for strength and galvanised to prevent corrosion. The base and cover are common for all uses and the hub plate is specific to the stud spacing of the hub. |
