An apparatus for a curtain rod that is attachable to a ceiling or to a wall and that possesses graspable holders slidable along a sliding rod of the curtain rod and supportable by the same, which graspable holders have devices for holding a curtain. The curtain rod has a ledge-shaped holder base extending along the length of the curtain rod, through which screws are received for fastening the holder base against the ceiling or wall. From the holder base, a ledge-shaped neck extends that supports the sliding rod. An obtuse angle is formed between the holder base and neck, in the space formed between the wall or ceiling where the curtain rod is fastened. At the top, the holders have flanges, at least one flange of which is shape-adapted to the cross-sectional shape of the sliding rod and possibly to spring apart from the other flange.

A curtain changing apparatus and method of use thereof includes a curtain retrieval arm engageable with a curtain track to allow the transfer of a curtain between the curtain track and the curtain retrieval arm. A removable insert is adapted to bridge the full or partial cutout section of the curtain track for normal use of the track, and an insert retrieval tool is adapted to enable removal and replacement of the insert from ground level.
