Abstract: Herein described is apparatus useful as roller assemblies for sliding structure such as a door or a window which engage tracks in the door or window frames. The structure comprises a frame insertable within the outer frame of the sliding structure which is generally U-shaped and comprises a roller rotatably mounted within the U-shaped frame. A U-shaped support supports the roller within the frame and includes a pair of extensions which are insertable through slots within the U-shaped frame on either leg thereof. Means disposable through the top of the frame engages the support structure for adjusting the limit of travel of the structure of the support within the U-shaped guide frame slots. A spring is included between this support and the frame to bias the wheel support and the wheel away from the frame.
