Spare Oar Grips are made of shock-absorbing stretch nylon that loops around oar frame side rail and buckles over spare oar with brightly colored side-release buckle. Releasing the buckle frees the oar. Metal Snap Swivel holder has spring-loaded collar and a length of polypro strap. Loop the strap around your frame rail, then around the spare oar, and hook the sewn-in loop at the end to the snap. Lifting the collar frees the snap, the strap, and your spare oar. Use one pair per oar.
