Thompson Handcuff Corporation now offers "A new level of restraints" with the TRI-MAX Handcuff range of chain & hinge style handcuffs and leg cuffs, with its innovative PickshieldXLS System. The Thompson TRI-MAX Handcuffs offers a High Security Handcuff, at a budget friendly price, with NIJ ceritfication. The Thompson TRI-MAX Handcuff is hardened to an R 44, which is probably the strongest in the industry. Add to that the original backloading feature and the Thompson TRI-MAX is the next generation of restraints. The Thompson TRI-MAX system combines a unique double shackle which rides through the cuff that is engaged by a multi tooth retaining system AND a steel rail, that not only reinforces the shackle strength but also when moving through the handcuff lowers the PickshieldXLS® and hides the rear retaining teeth making is highly pick resistance.
