Make unauthorized access nearly impossible. These hinges keep the leaves locked together, even if the pin is removed or broken. When the door is closed, the security stud engages so the door can't be lifted off. The pin is accessible only when the door is open. To remove it, loosen the set screw and the pull out the pin from the bottom of the hinge. For added security, hinges mount with tamper-resistant Torx screws, which require a special tool to remove. They work with or without a door closer.
