The invisidoor concept stands for the invisible integration of the door fitting in both the door leaf and the wall, without visible techniques. The modular aluminum door frame need to be plastered, and is available for inward and outward opening interior doors with door thicknesses options of 40, 44, 50 or 54mm. The door frame profiles of 6m long can be sawn for interior doors up to 4000mm high and 1250mm wide. The internal corner joints provide a fixed and seamless connection between the door frame profiles. Through utilizing adapters, the position of each neo hinge and the lock plate can be chosen freely. Due to this technique the selection between a left or right door, after incorporation of the invisidoor 2.0, remains free of choice.
