The potential criminal tries to break into the older vehicle through the gap in the door seal (door seals being poorly designed in older vehicles). The criminal encounters an additional type of seal on the inside of the door which is different to usual. Criminal perseveres and surprisingly the plastic strapping is allowed to pass through the seal and over the door lock mechanism - but when the criminal tries to pull on the strapping which is necessary to open the lock the strapping simply won't move - it has become trapped in the fibres of the seal and rendered useless. A one way seal – allows in but not out; preventing the crime taking place and also capturing evidence of the crime.The seal has layers of material; rubber, foam and natural matting, meaning the seal is breathable but will not let water in.
