Agostini’s Orama minimal frames are also exclusive in how they move: the door sashes glide along stainless-steel tracks with special dollies (also in stainless steel) with a double wheel on each side of the door (the number of dollies is increased for doors weighing over 350 kg).

This allows each sash to slide on at least eight wheels in a way that is muffled, almost silent. This system is also available with a motor drive, and can be integrated with home-automation solutions. 

The high-resistance stainless steel dollies are installed directly in the door to facilitate maintenance and cleaning, which can be done with a normal vacuum cleaner.
