Pemko DFM83 Full-Mortise Continuous Geared Hinge, 83" Length, Dark Bronze Anodized Finish

The Pemko DFM83 is a full-mortise continuous geared hinge engineered for high-traffic commercial openings where reliability and long service life matter. Measuring 83 inches in length with a durable dark bronze anodized finish, this hinge distributes door weight evenly along its full height, reducing stress on the frame and virtually eliminating the sag and wear common with conventional butt hinges. Its concealed geared design fits neatly into a mortised edge for a clean, finished appearance, while the anodized aluminum construction resists corrosion and everyday abuse. Ideal for institutional, educational, and commercial buildings, the DFM83 delivers smooth, quiet operation across countless open-and-close cycles.
