Xtreme Zip Ties, from Cobra Cuff manufacturer Milspec Plastics, can be folded for storage and double locked for pick-proof security, similar to the Cobra Cuffs but with a single strap. The double lock also helps prevent accidental over-tightening during transport of suspects, reducing officer liability. Using the same rubber-based polymer, Xtreme Zip Ties are also cold temperature stress-crack resistant for maximum hold under extreme temperatures. Xtreme Zip Ties are available in special camouflage color and glow-in-the-dark versions.
