The Peerless Model 850 provides additional restraint by more effectively restricting hand and arm movement. The Model 850 has the ability to fold flat for compact storage. It has a 10% larger inside perimeter then the Model 700 and Model 750. The color finish helps to prevent equipment loss by allowing iniduals, agencies or departments to more easily identify and track property. Color can also be used to enable or reinforce a classification system such as threat level, medical condition, jurisdiction and more. Also available in red, blue, yellow and pink. The color coating is applied using a process called Electrolytic Polyurethane Plating (EPP). EPP fully coats restraints inside and out without interfering with the lock mechanism or jaw swing-through. The durable EPP finish is resistant to chipping and scratching. The rust resistant EPP finish exceeds the National Institute of Justices 12 hour salt spray testing standard. The Model 850 has been approved by the National Institute of Justice. It comes with a lifetime warranty for manufacture defects. Two keys supplied. Made in USA.
