Transporting inmates accross the country is one of the most dangerous duties imaginable! Four point (hands and feet) restraint is a must! A belly restraint belt is a must for keeping those hands under restraint and close to the body, especially when uncuffing one hand at the hospital for medical purposes. The other hand can be remain restrained in place. I like the belly chain because at the hospital I can anchor that uncuffed cuff to just about anywhere on the belly chain. The chain is well constructed and works well with the black or blue cuff box.
