The Cable Seal 500 is a cable seal certified to ISO/PAS 17712, class H, designed for containers in intercontinental transport. Its flexible 5 mm cable also fits bent or damaged locking points where a bolt seal will not go through. Once closed, the seal can only be removed by cutting the cable.
The galvanised steel cable has a diameter of 5 mm and a length of 300 mm. It is braided from several layers of thin wires. Combined with the aluminium body, this gives a breaking strength of 1,900 kg.
When cut, the braided cable frays. As a result, the seal cannot be reused, and any attempt at tampering is immediately visible.
The independent MIRDC laboratory has tested the Cable Seal 500 and certified it to ISO/PAS 17712, class H (high security). The standard sets requirements for breaking strength, unique marking and production quality. The letter H on the seal indicates its classification.
The seal meets the requirements of C-TPAT, the US programme for secure supply chains. For containers bound for the US, this programme requires a seal with H certification. UK customs authority HMRC also accepts the Cable Seal 500. In addition, the seal complies with Clause 6 of ISO/PAS 17712.
Each Cable Seal 500 is printed with CS500 SEALED and a unique sequential number. Navacqs and the manufacturer together ensure that every combination is produced only once. As a result, each seal can be traced.
It is possible to make the Cable Seal 500 even more distinctive by printing your own text or logo on it. Below are the available customization options for this model:

You use a Cable Seal 500 for sealing containers where maximum security is needed. This cable seal is ISO 17712:2013 certified and suitable for international transport.
The seal is mainly used for containers with valuable cargo, or during transport where the container is transshipped multiple times.
This means a container moves from one mode of transport to another along the way, for example:
from ship to truck
from truck to train
or between different terminals at a port
At each of these moments, the container is physically moved. These are moments when extra control and security matter.
You choose a Cable Seal 500 when a higher breaking strength is needed. The 500 has a 5 mm cable and a breaking strength of 1,900 kg, while the 350 has a 3.5 mm cable and 1,250 kg.
In practice, this means the 500 withstands heavy loads better and is harder to break. The 350 is often sufficient, but the 500 is chosen when extra assurance is needed.
The Cable Seal 500 has a breaking strength of 1,900 kg. This means the seal can't be broken by hand, and heavy tools are needed to remove it.
This makes it one of the strongest cable seals in the range and suitable for applications where a standard seal doesn't offer enough assurance.
The Cable Seal 500 fits through most container locks, even when these are slightly bent or damaged. The 5 mm steel cable is thick, but still flexible enough to thread through openings.
In situations where a bolt seal doesn't fit through an opening that's too narrow or skewed, a cable seal is often the solution.
