A holder (1) for track rollers (4) or similar runner devices capable of being displaced along tracks (5) extending along the path of movement of a moving door panel or some other covering element. The invention permits, amongst other things, the use of a single type of roller holder, irrespective of the curvature of the guide tracks. Each track roller (4), etc., is supported by a swinging arrangement (6) attached to the door panel, etc., so that the track rollers (4) are capable of being adjusted to a desired position relative to the track (5) in question. |
