The OMNI Fire Door Hinge is a certified and durable hinge system suitable for fire doors, emergency exit doors, and heavy-duty doors. Manufactured entirely from steel and sheet steel, the set consists of a spring-loaded hinge and a non-spring hinge. The spring mechanism enables the door to close automatically, helping to keep it closed in the event of a fire. Its adjustable spring tension allows the closing speed and resistance to be adjusted according to requirements, while its robust construction ensures reliable and long-lasting performance.
