http://www.saferkiting.com just released a belt webbing with velcro so you can fit your shackle easily and can adjust it on your harness hook. Simply installation.
nor fotos available yet, but you may send an e-mail to belt@saferkiting.com and ask for it.
As soon as I get some, I will post them.

the part with the eyelet of an used adjustable harness line does a great job as well ! I´ve cut the loop from a Cabrinha Mono Svivel, reversely mounted it to the spreader bar, connected the Wichard and benefit now from the easily rotating double-pivoted system !

aloha
