FixFax - an innovation in the field of door automation. The FixFax door buffer is flush-mounted into the floor. When the door is opened, the door buffer automatically lifts out of the base plate and lowers again during the closing process. The flush FixFax door buffer (Type B) appears very aesthetic and discreet. It does not pose an obstacle when cleaning the floor or walking over it. This clever innovation operates with magnetic fields and has been registered by its developers as a patented system. With a light holding function, it is suitable for doors with a maximum door leaf thickness of 10 mm when combined with door closers, but does not provide a holding function.
