The Pemko FM_HD1 Full Mortise Continuous Geared Hinge is designed for new door installations that need strength, safety, and smooth operation. Because it spans the full length of the door and frame rabbet, it distributes weight evenly and reduces stress on the door. In addition, it hides both leaves, giving a clean appearance and increasing security.

Moreover, the inter-meshing gear design provides a larger bearing surface, which extends the life of the hinge. Furthermore, the anodized aluminum construction creates a harder and longer-lasting finish. Also, the hinge can be cut to length in the field for a precise fit without extra tools. In addition, optional modifications such as electric, hospital tip, and FirePins make it versatile for specialized applications. Therefore, it is ideal for schools, hospitals, commercial buildings, and other high-traffic areas.
