Updated for 2014, Safetyhander hand restraint mitts are designed to be used with handcuffs. Mitts are secured with two separate locks: a knurled thumbscrew for quick security and a handcuff key lock to double lock mitts. These fast securing, non-metallic mitts are ideal for prisoner transport, containment, and security checkpoints. In just a few seconds, an officer can secure each hand of a prisoner, which prevents seizing guns or escaping handcuffs. Click here for video.
