Description:
Cable Seals are designed for single use and leave clear evidence of tampering, making them widely used in security control applications requiring traceability and accountability.Self-locking mechanism: Automatically locks upon insertion; removal requires specialized tools, and any unauthorized access leaves obvious signs of interference.Unique numbering and identification: High-security seals support laser engraving, printed logos, or integrated RFID chips, enabling full-process tracking and clear responsibility attribution, compliant with ISO 17712 standards.
Suitable for regulated applications: Used in electricity meters, gas meters, and container transportation to prevent theft, meter tampering, or cargo substitution.s. Self-locking Design: Most cable seals adopt a ratchet-type self-locking mechanism, which automatically locks upon insertion, allowing tool-free sealing. Once tampered with, clear evidence of damage remains, ensuring anti-tampering protection.High-strength Materials: Typically constructed from galvanized stainless steel wire , with a wire diameter of approximately 1.8 mm and an average tensile strength of up to 580 kg, offering excellent resistance to shear and tensile forces.
Wide Range of Applications: Suitable for various enclosed scenarios such as shipping containers, truck doors, electric meter boxes, distribution cabinets, and cable conduits, effectively preventing unauthorized access and environmental damage.
Secure Self-Locking Mechanism
The ST8304 cable seal is designed with a reliable self-locking system that automatically secures the cable once inserted into the locking body. This ratchet-style mechanism allows quick and tool-free sealing during installation. After locking, the cable cannot be removed without cutting, and any unauthorized attempt to open the seal will leave visible damage. This feature helps maintain cargo integrity and ensures clear tamper evidence for improved security control.
Durable Aluminum Alloy Lock Body
The seal body is manufactured from high-quality aluminum alloy, providing excellent strength while remaining lightweight and easy to handle. The material offers strong resistance to corrosion, oxidation, and environmental exposure, ensuring stable performance in transportation, logistics, and outdoor industrial environments. The durable housing also protects the internal locking structure from damage.
High-Strength Galvanized Steel Cable
The ST8304 cable seal uses a galvanized steel wire rope that provides strong resistance to cutting and pulling forces. The galvanized surface improves corrosion resistance and enhances durability in harsh environments. Multiple cable diameter options—including 1.5 mm, 1.8 mm, 2.0 mm, and 2.5 mm—allow the seal to meet various security requirements across different industries.
Permanent Laser Identification
Each cable seal supports clear and long-lasting laser printing for identification and traceability. Sequential numbers, company logos, barcodes, and QR codes can be added based on operational needs. Laser marking ensures that the information remains readable during transportation and handling, helping organizations maintain accurate tracking and asset management.
Certified Quality Assurance
Produced under strict manufacturing standards, the ST8304 cable seal complies with internationally recognized certifications such as ISO 9001 and ISO 17712. These certifications ensure consistent quality, reliable performance, and suitability for regulated applications including container security and utility equipment protection.
Flexible Applications Across Industries
Thanks to its adjustable steel cable and strong locking structure, the ST8304 cable seal is suitable for a wide range of security applications. It is commonly used for sealing shipping containers, truck doors, electric meter boxes, gas meters, distribution cabinets, and warehouse storage units. The flexible cable design allows easy installation in different locking positions.
Customization Options Available
To meet different operational requirements, the cable seal is available in multiple colors such as red, yellow, blue, green, and black, with custom colors available upon request. The standard cable length is 25 cm, and customized lengths can also be produced to fit specific equipment or sealing points.
Efficient Bulk Packaging
The ST8304 cable seal is packaged for convenient storage and large-scale use. Each bag contains 100 pieces, and cartons are available in quantities of 1000 or 2000 pieces. The compact carton size of 35 × 26 × 20 cm allows efficient transportation, storage, and inventory management for logistics and industrial operations.
