A track assembly for allowing movement of a flexible enclosure cover over an area to be enclosed as, for example, a body of water in a swimming pool. The assembly comprises a pair of spaced apart tracks mounted on opposite sides of the area to be enclosed with each being comprised of an elongate strip. Each track strip comprises a cable receiving channel with a gutter or debris trough located generally beneath the channel for collection of debris. Preferably, a slider can be located in the cable receiving channel for locking to the cable and for securement of the cover to the cable. The track can be constructed to also allow for lubrication of the cable receiving channel anabling a slider mechanism to freely move therein. When a slider is used, it extends into each channel at approximately a 45 DEG angle with respect to a vertical direction. In accordance with this construction, debris which might otherwise collect in the cable receiving channel will drop into the gutter and will not interfere with movement of the slider mechanism or the leading edge of the cover. The slider may be adjustably secured to a rigid body which is, in turn, secured to the leading edge of the cover, and which allows side-to-side adjustment of the leading edge. Adjustment in the 45 DEG angulated plane could reduce bending moment forces on the slider and track.
