8900 Series

The dormakaba 8900 Series is a heavy duty surface mounted door closer for institutional and high traffic commercial doors, ANSI/BHMA Grade 1 certified (American National Standards Institute / Builders Hardware Manufacturers Association). Its hydraulic control system provides a highly flexible door control system with full range spring power adjustment and backcheck, a narrow projection full cover and a flat form style arm.

The hydraulic backcheck protects doors and adjacent structures: its valve adjustment regulates backcheck intensity, and a backcheck positioning adjustment for parallel arm applications provides a consistent range similar to regular and top jamb applications. With the fully adjustable spring, the 8900 Series also meets barrier-free accessibility requirements.

The 8900 Series heavy duty, 10 million cycle closers combine over a quarter century of proven performance with modern architecturally styled aesthetics, and are backed by a 25 year warranty.
