If you like me recieved a new '03 bar with your '03 kites then you realize that the schackle and ring on this bar do not always release 100%. Well after some time looking through our local sailboat shop I think I found an easy fix.
First you need to cut or grind off the small ring that is causing the system to stick.
I have replaced this ring with a Wichard schackle part number 1242. This is a stainless steel bolt through the side type schackle rated to 1100lbs. This fits perfectly in the webbing that the ring was removed from and has a larger opening that does not allow the tip of the side release schackle to catch on. I played with a number of others and this one seems to work better than the rest.
Spend a couple of minutes and a few dollars and make you slingshot QR much safer.
