The free-standing sliding door of the libero 4000 series is now also available as a frameless solution. In this Walk-In configuration, the sliding rail and support bar are discreetly fixed to the wall by through a discreet joint. The glass is sealed with silicone along the wall and at floor level, removing the need for profiles or wall hinges. The result is a particularly clean and transparent aesthetic that integrates elegantly into the bathroom environment.
