Fixed closure sheet metal security seal for trucks, railcars, trailers, and cargo containers. Crafted entirely from sheet metal. Ideal for high-security applications. Trust GUARD LOCK for robust and reliable sealing.


Discover GUARD LOCK, the fixed closure security seal designed for various applications. Crafted entirely from sheet metal, this seal offers a fixed length, providing robust sealing security with high tensile strength and resistance to bending. It’s the ideal solution for securing transit trucks, railcar wagons, truck trailers, or cargo containers.

GUARD LOCK represents a security solution in the form of a metal band seal, perfect for use on truck trailer doors and maritime cargo containers. It complements the security seal BALON SEAL, offering a more cost-effective alternative without compromising quality and sealing strength. The main difference lies in the closure system, with BALON SEAL having two systems, while GUARD LOCK features a single closure system.

Security seals with a fixed closure length tend to be more resistant to tampering than those with variable closure lengths, as they lack sliding parts, simply “clicking” into place for locking. This ease of use makes them a suitable choice for various requirements. Most fixed-length metal band seals can also be laser or mechanically marked and sequentially numbered for additional security.

Fixed-length security seals are often chosen for verification and control of access to protected objects, making them a preferred option for single-use security seals in transport applications or high mechanical strength closure or breakage-resistant security zones. When plastic security seals cannot meet specific security demands, fixed-length metal band seals like GUARD LOCK successfully fill the gap.

Typical applications for fixed-length sheet metal seals include securing valuable cargo in transit trucks, railway wagons, or trucks used in the cement and oil industries.

Choose GUARD LOCK for a secure, fixed-closure, and highly durable sealing solution designed to meet rigorous security requirements.
