What You Need to Know About Installing DORMA 8900 Series Heavy-Duty Surface Applied Door Closers

Each of DORMA’s 8900 Series closers includes sex nuts and machine screws for 1 – 3/8″ door. The closers have self-drilling screws for steel doors and frames as well as self-tapping screws for aluminum doors and frames. And each exposed fastener has TORX security. Each one is CSFM approved, meets UL10C requirements, is UL and CUL listed and ANSI/BHMA A156.4 Grade 1 certified.

The 8916 meets ANSI/BHMAS A117.1 and ADA barrier-free accessibility standards.

Therefore, you may need special assistance or parts in order to meet the requirement without affect the door closer’s performance.
