Pivot door with the practical advantages of a harmonic door

Basically, this system is the best of both worlds. The ease of use and luxurious appearance of a pivot door with the practical benefits of a harmonica door. We call it our “2+2 system” here internally because we always mount two panels per side. The operation is very simple: a second panel is mounted to a pivot door which hangs in a ceiling track. When the frameless pivot door closes, it simultaneously pushes the harmonica door closed. Very good application in recesses up to 4.00 meters without floor rails. Opened “only” on each side two panels totaling 10cm thickness against the walls and the rest is completely open!
