The Metal Flat End Seal is a strong and cost-effective alternative to the Tyden Ball Seal. This fixed length metal seal offers a high breaking strength of 45 kg and provides reliable protection for trucks, containers, and TIR cables. It can be easily applied by hand but requires cutting tools for removal. Thanks to its patented locking mechanism, any attempt at tampering results in visible damage, ensuring maximum security.
The Metal Flat End Seal features a specially engineered locking system designed to prevent manipulation. Once locked, the seal cannot be reopened without leaving clear evidence of tampering. Its one-time-use construction ensures that the seal cannot be reused, providing consistent reliability during transport operations.
While the Metal Flat End Seal shares many characteristics with the Tyden Ball Seal, it does not include the ball-shaped locking insert. This simplifies the design and makes it a more economical option, while still delivering strong and dependable performance. Although it is not customs-approved, it offers an excellent balance of strength and affordability for transport within Europe.
Constructed entirely from metal, the seal provides an impressive breaking strength of 45 kg. It cannot be removed by hand and must be cut with pliers or bolt cutters. However, application is straightforward — the flat end clicks securely into the locking mechanism, confirming a proper seal.
The Metal Flat End Seal is specifically designed for securing truck and trailer doors. Its fixed length ensures a consistent and tight fit during transport, even under heavy load or vibration. The 9 mm strap diameter fits easily through the eyelets of TIR cables, preventing unauthorized access to trailer tarpaulins or cargo areas.
Each Metal Flat End Seal is supplied with a unique serial number and permanent imprint. The standard version is printed with “SEALED” followed by an individual number. Both Navacqs and the manufacturer guarantee that each combination is produced only once, ensuring full traceability and eliminating the risk of duplication or fraud.
Note: Containers shipped outside the European Union must be secured with a High Security Seal compliant with ISO 17712:2013.

A Metal Flat End Seal is a metal fixed length seal with a fixed length and a breaking strength of around 45 kg. The seal has a flat strap and a simple click mechanism without moving parts such as a ball.
When closing, you slide the end of the strap into the head, where it clamps into place. After that, the seal can't be opened again without breaking it.
The seal is applied by hand and can only be removed with pliers.
Applications:
trucks
TIR cables
transport requiring a strong seal
A Metal Flat End Seal is used to seal trucks and TIR cables where a strong seal is needed, but customs approval isn't required.
The metal strap ensures the seal can't be broken by hand. This makes it suitable for situations where unwanted opening needs to be prevented, but no specific standard such as ISO 17712 applies.
In practice:
you thread the strap through the closure or cable
you click the end into place
the seal stays intact during transport
opening is done with pliers
The Metal Flat End Seal has a breaking strength of around 45 kg. This means the seal can't be opened by hand.
The strength comes from the metal strap and the fixed locking mechanism that blocks the strap once inserted. Unlike plastic seals, the material doesn't deform under pulling force.
Comparison:
NSS560-L: 14 kg
Plastic Truck Seal: 28 kg
Metal Flat End Seal: 45 kg
Tyden Ball Seal: 52 kg
The Metal Flat End Seal and the Tyden Ball Seal are both metal fixed length seals, but differ in approval and locking mechanism.
The Tyden Ball Seal is customs approved and used for transport within the EU. The Metal Flat End Seal doesn't have this approval and is used for standard transport without customs requirements.
The mechanism also differs:
Tyden → closure with a metal ball
Flat End → simpler clamping mechanism
The Tyden is also slightly stronger (±52 kg vs 45 kg).
Seals that can't be opened by hand are usually made of metal or have a high breaking strength. These seals stay intact until removed with pliers or cutters.
Metal fixed length seals, such as the Metal Flat End Seal, have a breaking strength of around 45 kg. This makes them resistant to pulling force and impossible to pull loose without tools.
This type of seal is used when:
it needs to be prevented that someone opens the seal by hand
force may be placed on the closure
a plastic seal isn't strong enough
