High-Performance Cable Seals | Tamper-Evident Security for Global Supply Chain Applications
Our cable seals are high-security, single-use locking solutions developed to safeguard cargo and assets during transportation and storage. Designed to meet global standards, they provide effective tamper evidence and ensure full traceability across logistics operations.
The seal combines a heavy-duty locking body with a high-tensile steel cable made from galvanized or stainless steel materials. Available in multiple diameters and customizable lengths, these seals adapt to various applications. The internal locking system features a multi-barb anti-retraction design, enclosed in a durable ABS or PA66 housing, providing high resistance to pulling force and environmental conditions.
Each cable seal is marked with a unique laser-engraved code for identification, supporting tracking and anti-counterfeiting. Custom logos, barcodes, and QR codes are available, along with multiple color options. Certified to ISO 17712, C-TPAT, ISO 9001, and RoHS standards, they ensure compliance with international logistics requirements.
Easy to install and operate, the seals require no tools and can be applied quickly. Once locked, they cannot be reused, and removal requires cutting tools, leaving visible damage. Suitable for logistics, shipping, utilities, and industrial sectors, these seals also support OEM customization.
