Spring hinges are self-closing door hinges designed with an internal spring mechanism that automatically returns the door to its closed position. Commonly used in residential and commercial settings, they provide convenience, safety, and improved energy efficiency by preventing doors from being left open. Spring hinges offer adjustable tension to control the closing speed and force, ensuring smooth and reliable operation. Durable and easy to install, they are ideal for high-traffic areas, screen doors, and spaces requiring enhanced privacy or controlled access.
