The car or ball end security seals are steel strap seals. A latching mechanism, a piano-wire loop that captures both ends of the strap, is located inside a crimped ball at one end of the strap. The tip of the seal is designed to extend through the lock housing and can be easily viewed through a special sight-inspection hole in the housing. The company’s name, logo, and sequential serialized identifiers can be embossed on the seal strap. Once the car/ball end seal is in place, it should be checked to ensure that there is a proper amount of end play in the latching mechanism. The seal is destroyed when it is removed for examination. The person conducting the postmortem examination should compare the removed seal to a sample seal and carefully inspect the exterior and interior surfaces to detect forgery. The ball housing should be opened to verify that all the internal parts are present.
