Solution: Destra designed a two piece moulding which clips together to form a secure, tamper-proof fixing. A model was made for evaluation before production tooling was started. To date, over six million components have been supplied in a variety of attractive colours. These colours are, of course, based on cadmium free additives, to provide a totally non-toxic product. This product has been so successful that further tooling has now been made to increase production.
