The Squids 3130 Coiled Cable Lanyard with Carabiners features a sturdy, PU-covered aircraft cable with a coiled design that helps to prevent snags, tangles and other tripping hazards. Stainless steel, manual-screw lock carabiners on both ends utilize a patent-pending captive-eye, swiveling-carabiner attachment system that reduces recoil force to prevent aggressive snap back, while further helping to minimize cable tangles. Designed to be used with Squids 3133 Barcode Scanner Loop Attachments (sold separately). Third-party certified to a 2:1 safety factor.
