Swing Clear Self-closing Hinges

Swing Clear Hinges are also known as offset door hinges or expandable door hinges. The unique leaf shapes can maximize the door openings by “swing away” the doors for a specified distance. Self-closing door hinges ( aka spring hinges ) can automatically close the door. More importantly, the self-closing function is the key feature for fire-rated doors. Waterson swing clear self-closing door hinge combines swing clear hinge type and self-closing attribute together, providing a much better door experience in wheelchair-accessible doorways like hospitals, hotels, nursing houses to name a few.
