Security Hinges

For use in areas where there is a clearly identified risk of self-harm.

Built in hinge bolts (dog bolts) prevent the opening of a door even if the hinge pin is removed or the hinge knuckle is cut completely away.

High level security is achieved with the flush welding of the hinge pin at either end knuckle, with additional weld fillets preventing the hinge knuckles being forcibly uncurled.

The hinge pin can be secured in place either by spin riveting the hinge pin to the button tip ends, or by pinning the hinge pin to the hinge knuckles on one half of the hinge using either a dowel into a blind hole, or threaded fasteners.
