Continuous Hinges

When it comes to maintaining proper door alignment, supporting heavy or high-traffic doors, and extending the life of your entryways, continuous hinges are a superior choice. Also referred to as piano hinges, these full-length hinges run the entire height of the door, providing consistent support and eliminating the stress points and sagging associated with traditional butt hinges. At Bay Safe & Lock, we furnish and professionally install continuous hinges on commercial, industrial, and institutional doors—whether as part of a new hardware upgrade or as a retrofit solution to fix alignment or closing issues.
​
Why Choose Continuous Hinges?
 

  Even Weight Distribution
By spanning the full height of the door, continuous hinges distribute the door's weight evenly across the frame. This dramatically reduces wear at the hinge points and minimizes stress on the door and jamb, preventing long-term damage.
​
  Improved Door Alignment
Continuous hinges help keep doors straight and properly aligned, especially in high-use or heavy traffic environments. This ensures smooth opening and closing, prevents gaps, and supports tighter seals for security, insulation, and fire rating compliance.
 
  Increased Durability
These hinges are built for longevity. With fewer moving parts exposed to wear and tear and no heavy reliance on individual hinge screws, continuous hinges last significantly longer than traditional hinge setups—often outliving the door itself.
 
  Enhanced Security
Because the hinge spans the full height of the door, there are no exposed hinge pins that can be removed. This makes forced entry much more difficult, adding a layer of tamper resistance.
 
  Code Compliance & Safety
Continuous hinges are often used in fire-rated doors, hospitals, schools, and public buildings where ADA compliance, fire codes, or long-term reliability are required.
