Cable seals are typically used to secure trailers, tankers, rail cars and containers; they provide robust security for unattended cargo, and can establish and maintain chain of custody with serialzed numbering schemes.  Our cable seals come in two main forms, fixed length and pull-tight.  Cable seals can be made with any thickness of cable from 1/32" up to 1/4 inch, and in any desired length.  The pull-tight seals allow users to snuggly fit the seal into a hasp, then tighten securely by pulling on the free end.  Fixed length seals are made specifically for repeatable, known-length applications; they lock exactly at the same place every time.  Both fixed length and pull-tight seals have laser engraved numbers and can also be bar coded and customized with logos and unique images.
