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.
