We were looking for a Glaschiebetür that fits against an existing door lining. We have the leadership backed up by 19 mm and so get the perfect door. The assembly is for two - weight of 10 mm disc is quite unwieldy for one person (-: - not a problem if you have the right plugs for wall The whole system is easy to install, the quality is great - we have to. the lower guide concerned from the hardware store an aluminum U profile, is better than the small guide piece that came. I can this door only highly recommend. Price / performance is outstanding. The contact of the supplier is working properly, responses obtained at short notice on its questions. Again 5+
