Abstract: A carrier slide is provided for window coverings and includes a main body, at least one vertical roller assembly, and at least one horizontal roller assembly. The main body includes at least one compartment defined therein. At least one vertical hole is defined in an upper end thereof and communicated with the compartment, and at least one transverse hole is defined in the upper side thereof. The vertical roller assembly includes a first roller rotatably received in the compartment. The first roller has a diameter greater than a width of the main body and smaller than a width of a track so as to be in a rolling contact with two inner lateral walls of the track. The horizontal roller assembly includes a second roller rotatably attached to a lateral side of the main body. The second roller is in a rolling contact with the inner face of the bottom wall of the track.
