Details: Waterson K51M Stainless Steel Self Closing Hinge

Commercial self-closing hinges need to handle the daily rigors of frequent use. Waterson Stainless Steel Closer 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. Additionally, Waterson hinges meet all ADA codes concerning speed control, closing force, and door clearance.
