How does it work:
The unique simplicity of the Hingemate® security stud design allows the user to replace one screw on the three jamb hinge leaves with a Hingemate*. In closing the door, the Hingemate® pins enter the door side of the hinge leaves and act as impenetrable deadbolts. Hingemate® provides safety and security of your commercial property that will last a lifetime. *Hingemate® can also be installed on steel doors with wooden doorframes.
