A sliding panel system is disclosed. The system includes a fitting assembly designed to fixedly secure a first panel to an elongate rail member, and a carrier assembly designed to moveably secure a second panel to the elongate rail member. The system facilitates the lateral movement of the second panel with respect to the first panel. The carrier assembly includes at least one carrier unit including a housing with an inner volume, at least one roller unit configured in an upper portion of the inner volume, at least one guide member configured in the inner volume, and an opening extending across the front of the housing and adapted to receive a longitudinal portion of the rail member. The at least one roller unit and the at least one guide member are concealed within the housing when the housing is viewed from a perspective perpendicular to the front of the housing.
