Security bolt seal

Bolt seals are most commonly used to secure sea freight containers as well as trucks and trailers. Offering far more security than a traditional lock, bolt seals are made of extremely tough materials and cannot easily be forced open. More importantly, tampering can easily be proven. The plastic-coated bolt and locking bush are laser marked with identical sequential numbers, essentially preventing attempted covert part swaps, or other means of subterfuge following tampering. Of course, proper security protocol must be implemented and adhered to in order for tamper detection to be effective.Bolt seals close easily with finger pressure, but require bolt cutters to remove. Often used on shipping and freight containers or for other heavy duty sealing applications, bolt seals are considered a high security, tamper evident seal.

High security container bolt seals are simple to use, and are an effective theft and tampering deterrent. To use, simply slide the pin, or bolt, through the latch hole and into the locking cylinder, and push until the locking mechanism snaps. Be sure to pull on the pin and cylinder to be sure that the bolt seal has properly locked. If you are installing the bolt seal vertically, be sure that the locking cylinder is positioned on the bottom.
Before locking the bolt security seal, rotate the pin and cylinder so that the serial number on both are facing outward, where they can be easily seen.
If you are using a container bolt seal on a very large latch hole, you may need to use heavy duty washers on the bolt seal pin, sized so that the washer is larger than the latch hole. Using washers in this way helps preserve the tamper evident nature of the bolt seal, because, although the washer can be removed through cutting, it cannot be replaced without breaking the bolt seal itself.
