💡 How do you properly space out concealed fire hinges on tall doors?
Installing these hidden hinges requires careful planning to meet safety codes and keep your door moving smooth.
You want the right spacing so every hinge carries its share of the weight evenly.
- Calculate one hinge for every two feet of vertical door height to spread the load correctly
- Match your hinge count to the drywall or steel frame weight cap of sixty pounds per support
- Space the units evenly from top to bottom so the zero pinch design stays perfectly aligned
- Secure each mortised slot deep enough to block heat transfer during emergency drill times
