Presented herein is a novel sliding door system that that enables adjustment of at least two sliding doors relative to each other such that surfaces of the sliding doors create a substantially flush surface a support onto which the sliding door mechanism is mounted. The system includes at least one inner and outer sliding door slidably coupled to corresponding guide rails. The guide rail that is coupled to the outer sliding door is selectably moveable by a sliding door mechanism between a first and a second position. In the first position, a user can slide outer and inner sliding doors along said guide rails, whereas in the second position, a surface of the outer sliding door is substantially flush with a surface of said inner sliding door.
