The FixFax door buffer is recessed flush into the base. 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 stop thus has a very aesthetic and discreet appearance. It does not pose an obstacle either when cleaning the floor or when walking over it. The clever innovation works with magnetic fields and has been registered as a patented system by its developers. (Not suitable for metal doors!) - Use only in dry indoor areas!
