" Referring to FIGS.
1 and 2 the invented split stops 11 are secured at the terminal ends of conventional extruded aluminum swimming pool cover track 12 along opposite sides of a swimming pool 16 for arresting translation of sliders 13 captured and sliding within the "C" channel 15 of the track 12.
The sliders 13 carry the rigid boom or leading edge 14 which spans the width of the swimming pool 16 holding the front edge 17 of the pool cover 18 above the water surface 19.
The sliders 13 are secured by screws to cables 20 extending from the beaded tape side edges 25 of the pool cover.

2, 11, & 12] FIG.
1 illustrates two split stops 11 located at each end of track 12 secured to the underside 21 of an overhanging coping 22 along one wall 23 of the swimming pool 16.
FIG.
2 illustrates a single stop 11 terminating a conventional deck track 12 proximate the cover drum 24 around which the pool cover 18 winds.
As shown in the FIGS.
1 & 2 the beaded tape side edge 25 of the pool cover 18 is captured and slides within the "C" channel 15 of the extruded aluminum pool cover tracks 12.
It should also be appreciated that FIGS.
1 & 2 show the location of invented split stops 11 only with respect to one of the tracks 12 secured along one of the sides of the swimming pool.
Identical split stops 11 must be located for arresting translation of the slider 13 captured and sliding in the "C" channel of the track 12 on the opposite side of the pool 16 at essentially the same longitudinal position such that, when arrested by the stops 11, the rigid leading edge 14 is perpendicularly oriented between the pair parallel tracks secured on opposite sides of the pool
