Tough enough for the heavy doors to warehouses, vaults, and other areas where security is critical. These hinges have a larger pin and thicker leaves and knuckles than other hinges to support more weight. Surface mount them to doors and frames.

Keep busy doors swinging smoothly and quietly without the mess of oiling them. These hinges have enclosed self-lubricating bearings for reduced friction and long life. Their screw holes are in a standardized half-moon pattern to match your existing door and frame. Fit the hinge leaves into cutouts (mortises) for flush mounting. These hinges work with or without a door closer.

Mount doors that don’t have cutouts (mortises) to frames that do. These hinges have a larger pin and thicker leaves and knuckles than other surface-mount hinges. They support more weight, provide more security, and withstand frequent opening and closing. Drill your own holes, or weld hinges into place for permanent mounting that resists stress and deters tampering.

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.

Drill your own holes, or weld these hinges into place to support doors that open and close frequently. With a larger pin and thicker leaves and knuckles than other hinges, they handle more weight. Use them on heavy doors to warehouses, loading docks, and other secure areas.

A turn of the screw adjusts even the heaviest doors to compensate for warping or sagging. With a larger pin and thicker leaves and knuckles than other surface-mount hinges, these support heavy and high-security doors. They also withstand frequent opening and closing in busy industrial spaces.

No need to measure or drill new holes—these hinges will match your existing door and frame. Their screw holes are in a standardized, half-moon pattern that’s identical across manufacturers. Fit the hinge leaves into a cutout (mortise) for flush mounting.
