CasePlus Design is a system for professionally housing technical door components and other elements of building technology. It is installed together with the door frame. The various technical components are protected yet easily accessible for modification and maintenance. This can be done by simply removing the cover of the steel frame (door frame) when the door is open. The different modules and door operators can then be serviced, exchanged or added to. The wall remains completely undamaged. The space needed for the electronic modules and switches is concealed behind design-oriented glass tiles.
