The CUFF-MAXX, from Boa Handcuff Company, is a high-security lock-and-key retrofit for existing handcuffs and leg irons. It uses a "restricted-access key" and a pick-resistant lock cylinder that are only sold to confirmed authorized personnel. The CUFF-MAXX is very lightweight, but also very durable and tough. It installs easily over existing equipment and comes complete with all necessary installation tools and instructions.
