The Rixson 91NDCP689RH is an overhead concealed door closer engineered for high-traffic openings where aesthetics matter. This offset-hung closer mounts inside the door frame and header, completely hiding the mechanism while delivering Grade 1 performance. The dress cover plate provides a clean aluminum finish that complements modern architectural designs.
Built for doors up to 250 pounds, this closer handles heavy wood, aluminum, or hollow metal doors in both interior and exterior applications. The right-hand configuration ensures proper installation orientation. Cast iron construction provides durability for high-traffic commercial environments where standard closers fail under constant use.
Grade 1 performance means this closer meets the most demanding ANSI/BHMA A156.4 door closer standards for cycle testing and opening force requirements. The adjustable spring mechanism allows fine-tuning of closing speed and latching force. For fire-rated openings, the UL 10C fire rating capability supports up to 3-hour assemblies when properly specified.
