ASSA ABLOY RR300 Clean is designed for medium-sized openings. It provides high air-tightness and fast operating-speed. Contactless Safety Edge prevents accidents even under high speeds. ASSA ABLOY RR300 Clean is also available with an optional contactless actuator that makes it possible to open the door with a simple wave of a hand. This reduces the risk of contaminants passing between your hand and the door side frames.
