Steels for springs - Import export

Black Prince is a tightening seal made of black polypropylene. It is classified as a tightening seal. The seal consists of a catch as well as a locking mechanism and a tail part. The locking mechanism contains a four-leaf spring steel collet, which provides reliable protection against tampering. The seal has an extended working length of 385 mm (15.16") for easy use on large and bulky objects. The lock provides reliable protection with a four-leaf collet made of spring stainless steel, where the leaves are slightly lifted upwards. When there is an attempt to pull the seal tail backward, out of the lock, the collet leaves drop down and cut the tail part off, thus rendering the product unusable. It means that you will always have visible evidence on the seal if there has been an attempt of external interference.
