** 5-Year Quality Guarantee; Resists Brittleness even after years of storage** Foldable, Double Locking, Rubber Based - Disposable Restraint Improves Officer Safety by making it virtually impossible to shim or break using blunt force techniques commonly used with nylon Zip Tie type restraints. The unique wedge shaped design of the Locking Clip also prevents accidental over-tightening of the cuffs during prisoner transport or a struggle. In addition; Cobra Cuffs reduces officer liability and is safer and more comfortable for the prisoner compared to stiff nylon or metal cuffs. The tactical advantage in fully assembled cuffs can be found in no other disposable restraint allowing immediate control by the officer. Why Rubber? Rubber helps prevent the stress cracking common with nylon zip ties when exposed to cold, heat or folding / creasing. Superior shelf life is an added benefit with Cobra Cuffs because our special polymer formula resists brittleness so well. Therefore we offer a minimum 5-Year Quality Guarantee for all colors of Cobra Cuffs. The Super Tough Rubber Based Polymer used in Cobra Cuffs also absorbs the shock and stress during a struggle -making the 400+ lb Tensile Strength more than sufficient to contain the most violent suspects.
