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.

The tightening seal Black Prince also has an additional protection feature - customized numbering applied by laser. The unique numbers are marked through the thickness of the seal's surface. Thus, this marking cannot be erased, removed, or counterfeited. The marking is applied to the catch of the seal and a protective cap on top of the locking mechanism. This cap protects the lock from external interference and makes it possible to monitor its integrity.

For ease of use on the bags, there are special tenons on the backside of the seal. They help to attach the seal in a convenient way.  Additionally, your logo, QR, barcode, etc. can also be laser-marked on the catch.

Advantages of the tightening seal Black Prince:

  • Secure spring steel lock
  • Special tenons for a secure fixture on bags
  • Lock with a self-locking mechanism
  • Patented product from the manufacturer

The tightening seal Black Prince is designed to protect against unauthorized access to such objects as:

  • cash-delivery bags
  • containers, luggage
  • storage facilities
  • transport, fuel tanks, and other facilities

Installation of the device is simple: you need to put the tail part through the eyelets or holes of the object and then pull it through the collet lock. To ensure a secure fastening, it is recommended to put the free end through two additional holes on the seal catch.
