What is Self Closing Door Hinge
Self-closing door hinges combine the function of an overhead closer into one compact and attractive component. Some models include optional hold-open and door-stop features. They’re ideal for commercial doors, gates, and frameless glass doors, offering both functionality and aesthetics in a single unit.
How Do Self Closing Door Hinges Work
Self-closing door hinges with a mechanical-hydraulic hybrid design combine spring tension and fluid control to ensure smooth, automatic door closure. Here's how each part works:
Mechanical Operation:
Uses a torsion spring and braking system to close the door. Speed is controlled mechanically. Durable, fire-rated, and ideal for high-cycle use.
Hybrid Hydraulic:
Adds a hydraulic reservoir to soften and slow the door's movement. Offers smoother closing, especially in windy or high-traffic areas.
