The Model 7082, an addition to Hiatt's Blue Box Transport System, increases the rigidity of chain-style handcuffs during transport or detention, and keeps the keyholes covered for increased security. The double locks can be activated from outside of the box, enabling faster and easier access to cuffs while they are in use. Additionally, to immobilize a detainee's hands, the Model 7082 allows a belly chain with a Martin Link to be inserted.
