Product Overview
Steel wire seal locks (also known as cable seal locks) are high-security physical sealing devices consisting of high-strength steel wire rope and a secure locking mechanism. Designed for single-use protection, they effectively prevent unauthorized access through a one-way locking system. They are widely used to secure containers, cargo boxes, meter boxes, tanker trucks, equipment cabinets, and other assets requiring robust tamper-evidence.

A: How long will the unused seals last? A: 3 to 5 years if kept in a cool, dry place away from high humidity and direct sunlight. The corresponding usage records (sealing logs) shall be retained for at least 2 years since applied.
Q: Are there any special requirements for seals for the transport of live animals?
A: They must also be applied to ventilation and feeding ports to prevent unauthorized removal or theft of live animals. In addition, the sealing materials must be non-toxic and totally harmless to wildlife or livestock.
Q: What's the difference between a security seal and a normal lock?
A: A security seal is a tamper-evident device intended for single use to provide conclusive evidence of unauthorized entry. But a lock can be opened and closed over and over again with a key or code to allow or deny access on an ongoing basis.
