Designed for light-duty residential and interior applications, the SC90 Series closers deliver a smooth and reliable performance. A pre-set spring size provides easy installation. The closer has three mounting options and is non-handed for left- and right-swinging doors for versatility. A single-piece cast aluminum body minimizes leaks, the most common door control failure. Materials include sturdy heat-treated steel pistons and heat-treated pinions. The SC90 Series is also ANSI/BHMA A156.4 Grade 3 certified for durability, UL listed and backed by a 10-year warranty. The closer uses a UL10C approved fluid for its hydraulics and is UBC 7-2 fire test compliant. The SC91 in particular meets the American Disabilities Act (ADA) and ANSI A117.1 requirements.
