The evolution of Palo Alto I-Box, Palo Alto Free is the new wardrobe concept that calls for the use of doors directly supported by floor-to-ceiling posts that form the structure. This simple system for closing niches or separating spaces sustains a series of accessories for the compartments, similar to those of the Palo Alto I-box. The product is compatible with all the doors already contained in the Palo Alto I-box system, and with the evolution of the Rex door, featuring an innovative opening mechanism, similar to a pantograph, that permits the movement of one or more pairs of doors from their closed position to total 180° opening, placed over the doors of the adjacent compartment. The result is the total opening of spaces of about two meters.
