The BC-03 Navaloop Bolt Cable Seal is a patented product combining the security of a cable seal with thefunction and ease-of-use of a bolt seal.  It is based on a High Security bolt seal standard, as per ISO 17712, incorporating a "door to door" (DID) cable seal. The cable part of the Navaloop is made of NPC (Non Pre-formed Cable) which "blooms" when cut.  Incorporating a DID cable creates a verifiably secure sealing loop, and addresses the vulnerabilities of container design which regular seals do not.

The BC-03 is a tandem bolt cable seal with an anti spinning feature. It consists of a locking pin and lockingbush. The pin has a fixed length. The locking mechanism of this seal is of unique, original and patented design, not found on any other make of bolt seals. It consists of a steel locking spring of intricate claw like shape which located inside of an all steel locking bush. The claw like locking spring engages into a circumferential groove machined in the locking pin, gripping and securing it firmly. All the elements of the locking mechanism are made of steel, providing ultimate strength and hindering tampering before as well as after the seal’s application.  The locking bush and locking pin are coated by ABS plastic and can be laser etched with numbers, logos and bar codes. Tampering with Navaloop seals is virtually impossible for intruders and also deters insider collaboration in cargo theft and/or other wrongdoing.  The bush is standard marked with a 6 character alphanumeric consecutive seal number and logo or name which is laser engraved (depending on the chosen color and customer preference). The seal serial number is duplicated on the pin in order to enhance security.  This seal is available in various colors. Bar coding is optional.
