ASSA ABLOY - Marine supply a range of rack and pinion Door Closers, which are distinguished by their compact shape and they are very versatile. They meet the requirements of CEN guidelines TR 15897/DIN Spec 1104, which recommends a reduction in opening force by 40% by the time the door opening angle reaches 60o at the latest. This way the ASSA ABLOY rack and pinion door closers guarantee comfortable door opening due to the rapidly decreasing force progression. Doors equipped with these door closers can be opened more easily and with less exertion by the elderly and disabled, as well as children.
