The old Hiatt-Thompson Blue Box Model 7082 has been redesigned and renamed CTS Thompson Model 7084. The new box accommodates all standard chain handcuffs including ASP, but can now also be used on leg irons. It takes 2 boxes and 2 padlocks to turn a set of leg irons into high security restraints. The new box is easily identified by its darker navy blue color and nickel plated locking clip. The new blue box still has slots to double lock after the box is applied.
