We would like to fit concealed door closers to our back doors which regularly slam shut and consequently have cracked the external render around our door frames at our house. We are interested in the GEZE Boxer closers but would be grateful if you could advise if they are suitable for heavy wooden doors. Also can you advise if you can adjust the speed of close with these closers to provide a slow final shut to the door into the door-frame?
Geze Boxers are ideal for solid wooden doors. The version with power size 3 – 6 is suitable for doors with a leaf thickness of at least 50mm, maximum weight of 180kg and leaf width of no greater than 1400mm. There is one for lighter, smaller doors (the version 2 – 4). Both the closing force and the closing speed are adjustable.
