The cargo seal is a security bolt seal designed for tamper-evident container and trailer locking, featuring a high-grade Q235A steel pin and bush with an ABS cover. The total size measures 7.9 mm in length and 21.4 mm in width, while the marking area spans 7.9 by 75.5 mm, allowing for laser-etching or hot stamping of barcodes, numbers, or names. With a tensile strength of 20 kN, it meets the physical demands of securing containers, trucks, railway wagons, and other transport units.

Available in blue, green, yellow, or other custom colours, the seal is supplied in boxes of 10 units, with 25 boxes per carton. Each carton measures 49 by 32 by 15 cm and weighs 23.2 kg net, making it suitable for bulk shipping. The bolt seal mechanism locks by inserting the pin into the slot and pushing the barrel until it clicks, ensuring a secure fit that can only be removed by breaking the seal.
