Full Mortise Butt Hinges

Full mortise butt hinges are the most commonly used type of hinge on commercial doors. The hinge sits flush with the surface of the door and frame when installed, leaving a smooth finished appearance. Spring hinges are used for automatic closing of fire doors, when a door closer cannot be used.
