Waterson Corp

Commercial self closing door hinges need to handle the daily rigors of frequent use. Waterson stainless steel door 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 commercial self-closing door 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. K51M is a full mortise (butt) hinge; its leaves are fully concealed when a door is closed. It is also available with a protective, screw-on, weather-resistant cap for use in exposed, wet locations.
