In addition to the industry-standard adjustable cables seals, each CSS cable seal offers customized fixed-length options for customers with unique requirements. As with most CSS seals, these metal security seals allow you to select from a wide variety of colors, barcoding, and other enhancements to add extra layers of security and protection.
