The Unisto Metalo 25 is a durable cable security seal designed for sealing truck doors, tanker trucks, air cargo containers, rail cars, and shipping containers. Its robust construction and tamper-evident features make it ideal for protecting goods from opportunistic attack during transit and storage. Overview Specs Compliance Applications Built for strength and reliability, the Unisto Metalo 25 combines an aluminium alloy body with a high-quality steel cable and precision-engineered locking system. Its non-preformed cable unravels once cut, preventing re-use or re-sealing, while direct laser marking ensures clear, permanent identification. Available in multiple colours, each seal can be uniquely marked with a customer name, serial number, and barcode for efficient data capture and logistical control. Medium-heavy cutters are required to remove the seal safely.
