A rail and slider system comprising at least one rail having a longitudinal axis, a front, a back, opposite sides extending longitudinally of the rail, a top and a bottom, said rail being adapted to be mounted on a wall or other mounting surface with the back of the rail facing the wall, a pair of generally parallel spaced-apart tracks extending longitudinally of the rail adjacent opposite sides of the rail, said tracks having teeth spaced at intervals along the tracks, and a slider mounted on the rail for sliding movement along the rail, said slider comprising a body positioned on the front of the rail, at least a first pair of arms at opposite sides of the body having teeth thereon engaging selected teeth on respective tracks of the rail, the teeth on the arms being fixed and immovable with respect to the arms and the teeth on the tracks of the rail being fixed and immovable with respect to the rail, and a spring device on the body contacting the rail for urging the body and arms of the slider to move relative to the rail toward a locked position in which the fixed and immovable teeth on the arms are in engagement with respective fixed and immovable teeth on the tracks to lock the slider in a selected position along said rail, said body being manually movable against the urging of said spring device from said locked position to an unlocked position in which the fixed and immovable teeth on the arms and the fixed and immovable teeth on the tracks are disengaged to permit sliding movement of the slider along the rail to a different selected position whereupon the spring device, upon release of the body, causes the body and arms of the slider to move relative to the rail back to said locked position thereby to lock the slider to the rail in said different selected position.
