Oversized, rubberized end caps help prevent scratches and dents while the bottom cap features a custom ID area for the angler's contact information and rod type. The quarter-turn tenon style cap clicks shut and forms a seal that keeps out sand, gritand water. These new rod tubes bring fresh innovation that will safeguard your rod, and your trip.
