I was wondering if anyone one had any ideas on a way to lock in place the straps into the reel of a solar cover reel??? I ordered a solar cover reel from amazon. the straps rom the blanket "slide" into the grooves of the aluminum tube......... the thing is that while the system works very well at preventing the the straps from detaching from the pole, it does nothing for preventing the straps from sliding from side to side.... does anybody know if anybody sells something that would help??
