Abstract: A door swinging device that does not require fastening to a door for installation or use. The door swinging device includes an actuator housing that slidably accepts an actuator therein. The actuator housing is attached to a door hook that is configured to hang from the top of a door. The actuator can be operably and physically attached to an arm, bracket and door frame. The door swinging device swings a door by pushing or pulling the door with respect to a door frame upon activation of the actuator. A frictional fit of the actuator in the actuator housing combined with a frictional fit of the door hook over the door maintains the actuator in a stable position with respect to the door during operation.

Abstract: A sliding door support assembly having a preassembled track assembly including a split cylindrical elongate track having a flat surface on the top and a number of mounting brackets secured to the flat surface at spaced intervals and a number of support members for supporting an elongate track cover, the support members being mounted on said track assembly after the door has been mounted in the track assembly and being selected to correspond to a particular type of track cover.
