SAS International Marine Services is a leading distributors of Security seals.  Cable seals are high security seals used to seal shipping containers in a way that provides tamper evidence and some level of security. The Cable seals have a braided galvanized steel wire cable combined with an aluminum body consisting of a lock, a lock sleeve, a lock body, and a steel wire rope.

Security seals are commonly used to secure truck trailers, vessel containers, chemical drums, airline duty-free trolleys, and utility meters. Typically, they are considered an inexpensive way of providing tamper evidence of intrusion into sensitive spaces.

Cable seals allow for more versatile application, as they have variable length of the locking mechanism which can be customized by the cable length. Typical applications include sealing trucks and railway cars transporting valuable commodities. An internal locking mechanism prevents the cable from being retracted. Most cable seals are classified as security or high security level as to ISO 17712.
