Our "Pro Series" Sail Ties are made from a wider webbing material than our regular sail ties. They also have a larger twisted loop, one you can reach through to grasp the other end of the tie. This makes securing the sail tie a little easier. We also take the time to roll the edge on the tail of the tie and put in a bar tack to keep this free end from unraveling Pro Series Sail Ties are available in black, white and pacific blue. Just remember to tell me what color you want at the time you order.
