When you want to rig your boat with the double-pulley configuration- rig it with the best in the business. FLAT Rigs offers our 100% EPDM shock cord that carries our 3-year warranty outfitted with Ronstan’s stainless steel ball bearing acetal block double pulley. This sailboat racing pulley is more than capable of deploying and retrieving a double release clip configuration up and down your outrigger pole when the fishing gets hot. Our cords also employ a 316 AISI stainless steel snap hook on the anchor end that will remain rust free. The end result is- a durable, efficient, and good looking piece of hardware necessary for a great day of trolling.
