such that upper longitudinal edge 14 of main body 12 is disposed under awning sheet 130 adjacent to first longitudinal channel 112 and awning seam 133 as shown in fig5 although gravity will tend to urge main body 12 into this position in any event as discussed later herein when a suitable number of raintrough clips 10 have been installed along the length of awning reel 110 as shown by way of example in fig3 valance sheet 140 may be readily deformed as shown in fig5 to form a rainwater drainage trough or u201c raintrough u201d 145 lying in the generally u shaped space between outriggers 18 and main bodies 12 of raintrough clips 10 therefore rainwater flowing downward over awning sheet 130 will be directed into raintrough 145 which will carry the rainwater to a disposal point at either end of awning reel 110 drainage toward a preferred end of awning reel 110 may be achieved by differential adjustment of telescoping arms 120 such that one end of awning reel 110 will be lower than the other end alternatively raintrough clips 10 may be provided in different sizes with slight variations in the configuration of outrigger 18 such that raintrough 145 will be formed with a slope or u201c fall u201d tending to direct run off toward a selected end of raintrough 145 the weight of the valance material resting on outriggers 18 not to mention the weight of any rainwater flowing into raintrough 145 will induce rotational forces tending to keep upper longitudinal edges 14 of main bodies 12 securely disposed in the crevice like space between awning reel 110 and awning sheet 130 thereby stabilizing the position of raintrough 145 relative to awning assembly 100 the installed position of lower longitudinal edges.
