Commercial Continuous Hinges & Geared Hinges
Distribute the weight of your door evenly and eliminate sagging with our professional continuous hinges. Designed to run the full height of the door, these hinges are the ultimate solution for high-traffic or heavy-duty openings. We offer a wide range of aluminum geared hinges and stainless steel pin and socket hinges in standard lengths like 83", 95", and 119", providing a lifetime of reliable service.
Which mounting type should I choose for my door?
Selecting the right mounting depends on your frame type and whether you are performing a new installation or a retrofit:
- Concealed (Full Mortise): The most common choice for new construction. Both leaves are hidden between the door edge and the frame for a clean, secure look.
- Full Surface: Ideal for retrofitting damaged frames. Both leaves are mounted directly to the face of the door and frame, making installation fast and reliable.
- Half Surface: One leaf is mortised into the frame while the other is surface-mounted to the door face. This balances a finished look with the strength needed for heavy doors.
If you are unsure of which type to select, Pemko has an excellent Continuous Hinge Selector Tool as a great reference tool.
Frequently Asked Questions: Continuous Hinges
What is the difference between Geared hinges and Pin and Barrel hinges?
Geared continuous hinges utilize interlocking teeth and a cap to distribute door weight across the entire length of the frame, making them the best choice for high-traffic commercial entrances. Pin and Barrel hinges (often called piano hinges) use a traditional central pin design, which is ideal for supporting exceptionally heavy loads and oversized doors.
Should I choose Stainless Steel or Anodized Aluminum hinges?
Material selection depends on the environment. Stainless Steel is recommended for corrosive environments, coastal areas, or outdoor gates due to its superior rust resistance. Anodized Aluminum is the industry standard for commercial storefronts and interior office doors, offering a lightweight, durable, and cost-effective solution.
Are your continuous hinges fire-rated and ADA compliant?
Yes. In 2026, building code compliance is critical for contractors. Our continuous hinges meet ADA standards for opening force and accessibility. Additionally, we stock hinges that comply with NFPA 80 fire ratings, ensuring they are "installation-ready" for fire-rated door assemblies in hospitals, schools, and commercial buildings.
