Abstract: The track for the panel of a sliding door or window confines a locating device with two resilient leaves which have first end portions secured to the bottom part of the track and second end portions normally extending upwardly into the path of movement of the rim of a wheel at the underside of the panel. The second end portions of the leaves are disposed between the first end portions and define a gap wherein the lowermost portion of the rim comes to rest after the rim has been caused to roll over one of the leaves and to be arrested by the upwardly extending second end portion of the other leaf. If the panel is to be shifted to a different position, it is pushed with a force which suffices to enable the rim of the wheel to depress the second end portion of one of the leaves whereupon the rim rolls over the one leaf toward a different position. A foot can be clamped to the track to positively prevent the panel from moving beyond a selected position.
