Carbon steel EPP finish Improved internal lock mechanism The Model 752 Oversize Chain Link Handcuff is available in a color finish. The color finish helps to prevent equipment loss by allowing individuals, 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. 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 Justice&';s 12 hour salt spray testing standard.
