Grade 1 | Heavy Duty | Clear Anodized Aluminum | Full Mortise

Upgrade high-traffic commercial doors with the Pemko CFM83HD1 83" Full Mortise Heavy Duty Continuous Geared Hinge.

Designed primarily for new commercial door applications, this heavy-duty continuous hinge distributes the door load across the full height of the opening, helping reduce door sag, binding, hinge wear, and alignment problems commonly associated with traditional butt hinges.

The full-mortise design mounts to the door edge and frame rabbet, concealing both hinge leaves for a clean architectural appearance. Its durable aluminum construction and clear anodized / satin aluminum finish provide dependable long-term performance in demanding commercial and institutional environments.
