FixFax - an innovation in door technology. 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 back down during the closing process. The flush FixFax door buffer (Type B) is very aesthetic and discreet. It does not pose an obstacle when cleaning the floor or walking over it. This clever innovation operates using magnetic fields and has been registered by its developers as a patented system. It does not have a holding function. Suitable for doors with a maximum door gap of 17 mm.
