From ASSA ABLOY Entrance Systems, the RR3000 XXL can be found in use wherever busy, large doorways are needed. This brilliant fast running door opens at high-speeds, even in doorways up to 6 m high. A special winding mechanism (Disc DriveTM) allows the door curtain to be wound without noise or wear. The flexible slats in particular offer a great benefit in daily use. They protect the door against possible collision damage and also provide noise insulation. The contactless photocell provides the necessary safety.
