K51M-450-A3 self closing hinges are designed to manage commercial closing demands while maintaining fluid and effective movement, particularly with obligatory fire rated doors. A typical 7’0 door utilizes three active Waterson Closer Hinges to create a perfect, self-closing system. Each hinge’s unique numerical panel allows the spring tensions to adjust precisely according to door weight and environmental conditions.
