buy some heavy duty velcro pads , the type that has adhesive on , do it all sell them , stick a small piece on pole where trigger will sit, and a piece on the trigger, then put jubilee clip on and tighten , the velcro will stop it spinning. get the type with water proof adhesive , they come in a pack of 2 strips , 1 are the hooks , the other is a fury strip that grips to the hooks. hope this helps
