Don't know PA2200 Nylon
For many years Fireballer sailors have had to make the decision whether to have a “double ended” spinnaker pole with a sliding central up-haul down-haul or a fixed “single ended” pole with the up-haul and downhaul fixed to the outer end. Our new poles, which people have dubbed the “Sayce-Rees pole” uses this collar to give the best of both systems.
The system can also be used on other classes where their rules allow.
I generally get this commercially printed in PA2200 Nylon and ask for the manufacturer to print them solid for strength.
