Pemko CFM83-HD1 Continuous Geared Hinge - Full Mortise Heavy Duty
The Pemko CFM83-HD1 is a high-performance Full Mortise Continuous Geared Hinge designed for new door applications where performance and security are paramount. Unlike traditional butts, this Heavy Duty hinge distributes the weight of the door uniformly along the entire length of the frame. This eliminates sagging and misalignment, making it the ideal solution for high-traffic environments. Finished in a Clear Anodized Aluminum, it provides a sleek, modern look while offering a massive 540 lb weight capacity.
High-Performance & Security Features
- Uniform Load Distribution: By distributing stress along the full height of the door and frame, this hinge prevents the common "sagging" found in high-frequency commercial openings.
- Smooth ADA Operation: Engineered with an operating force of 1/2 lb or less, ensuring accessibility compliance and effortless opening regardless of door size.
- Advanced Gear Mechanism: Features inter-meshing gear segments that provide 50% more bearing surface than standard hinges, significantly reducing wear and extending the life of the door.
- Concealed & Sight-Proof: The full mortise design conceals both hinge leaves when the door is closed. This provides a clean aesthetic and a sight-proof seal for maximum privacy in offices and restrooms.
- Durability and Hardness: The aluminum is anodized after machining, creating a harder surface that resists wear and friction in extreme-use settings like schools and hospitals.

Pro-Tip for Architects & Contractors
The Pemko CFM83-HD1 is the "gold standard" for lead-lined X-ray room doors and heavy oversized entrances. If you are retrofitting an existing door, please measure your clearance carefully, as full mortise hinges require a wider gap than standard butt hinges. For fire-rated assemblies, these hinges can be equipped with FirePins to meet stringent commercial fire codes. The thread-forming screws included make installation into hollow metal frames significantly faster by eliminating the need for manual tapping.
