Comfortable with safety – that's the integrated door closers from GEZE. They close your swing door gently and quietly and also slow down the swing in the opening direction due to their back check. You can always rely on the GEZE Boxer solutions for single leaf swing doors. You determine the closing speed. You can count on maximum safety with all integrated door closers. If you want extra convenience, then opt for the Boxer EFS 4-6 with electric free swing function.
