I designed Stoplock Compact for Metro products Ltd. They were looking for a more compact sister product to their already highly successful Stoplock car anti theft device. By attaching Compact tangentially to the rim of the steering wheel it allowed the product to be a much smaller size. This feature made Compact much easier to store safely within the car when not in use.
Compact featured innovative use of materials as the main body was an aluminium extrusion. This was then reinforced internally to guard against any criminal attack using commonly used tools.
Compact was a great success for Metro products and they sold many tens of thousands of units through various retail outlets including Halfords, Argos, Homebase. There was also an AA branded version.
