ABSTRACT:
A roller wheel assembly for a sliding closure has a wheel unit which is supported in a frame for vertical motion relative thereto when the assembly is installed in the closure. Means in the form of a wedge assembly which engages sloped surface means in the wheel unit are provided to vertically adjust the wheel unit relative to the track. The wedge assembly is adjusted sidewise by means of a screw assembly which is operated from the side of the frame. This causes wedge shaped surfaces of the wedge assembly to ride along the sloped surface means to afford a continuous and precise vertical adjustment of the wheels.
