The Blocker LP-FT is one of the safest and most reliable container seals available for international transport. This unique seal combines two security mechanisms in a single product: a bolt seal and a cable seal that are physically connected. Both components share the same imprint and sequential numbering, completely eliminating the risk of tampering or counterfeiting. The 10 mm pin and head are made from high-strength PP plastic, while the cable seal features an aluminum housing with a 4 mm steel cable that frays when cut, making reuse impossible.

Dual Security Design for Maximum Protection

The Blocker LP-FT provides dual-layer protection by combining the strength of a bolt seal with the flexibility of a cable seal. Its patented anti-spin system prevents the bolt from being unscrewed with tools such as drills, keeping the seal intact even under manipulation attempts. This dual design makes the Blocker LP-FT ideal for shipments that require maximum security and visible proof of integrity.

ISO 17712:2013 Certified

The Blocker LP-FT meets the international ISO 17712:2013 standard for High Security Seals. This certification confirms that the seal has been tested for tensile strength, material integrity, and tamper resistance. The ISO certification guarantees that the Blocker LP-FT is suitable for international container transport and meets the requirements of global customs and security authorities.

Globally Recognized by Customs and Security Programs

The Blocker LP-FT is approved by customs authorities worldwide and recognized by major international security programs such as C-TPAT (U.S.) and ISPS (maritime sector). This ensures compliance with the strictest global transport safety and security standards.

Steel Cable Frays When Cut: Reuse Impossible

The 4 mm steel cable is made of multiple braided wire strands that fray immediately when cut. This makes it impossible to reuse or repair the seal without visible damage. This mechanism makes any tampering attempt easy to detect and increases reliability during long-distance transport.

Usage and Personalization

The Blocker LP-FT is applied by fitting the bolt through the container’s locking mechanism and looping the cable around the door bar, creating a fully closed system that cannot be opened without visible damage. The standard configuration includes an orange bolt seal and a blue cable seal. Each seal is printed with a unique serial number and marking, and can be customized with a company logo, barcode, or specific numbering sequence.
