See the ball thingy on the quick release buckle of this belt? https://www.kayakwaveology.com/prod...MFCxxSnJhyF58X5LCh1jBdwE7hlBaO4R1jINwXT9OZJI0 My tow belt does not have one and MAN is it hard to get the buckle loosened in an emergency. I need a ball. There is a HOLE for the cord to attach the ball, but no ball. And I have no idea where to find such balls. Any suggestions? Thanks!
