Floor Spring Door
The Floor Spring Door is concealed installed into the floor, the door leaf can open freely inside and outside.
Almost invisible, yet fully functional: Floor springs ensure that the doors will close themselves after opening. They're just as good as overhead door closers where convenience and safety are concerned. All individual parts are built into the floor or the door. Floor springs are ideal when the door design should be as unobtrusive as possible - be it at elegant portals or in upmarket shop fittings.
