As the name suggests, the straps of the lightweight ASP Tri-Fold disposable restraint fold in three places, for ultra-compact storage on a belt or vest. When deployed, they provide wide open loops for fast and easy application. They're perfect for crowd control, military use, aviation security and other situations where traditional handcuffs aren't practical or desirable. The tri-fold straps are extra-wide, with smooth edges for safety, and run through a fully-enclosed ratchet block with a shim guard to prevent picking. Tightening the restraint is quick and positive, using either the included molded pull ring or optional, extra- long pull cord. Once tightened, squeezing the secondary compression lock buttons provides additional security. Once applied, Tri-Folds must be cut off-our optional Scarab Cutter is recommended for fast, safe removal. The latest generation of Tri-Folds incorporate a new polymer formulation-perfected after over a hundred prototypes-that won't dry out or get brittle, giving them increased strength and longer storage life. Tri-folds are available in black or high-visibility yellow, as well as a red training version that can be applied and removed repeatedly, without cutting.
