Universal Rod Replacement Cap fits most manufacturers' standard tenkara rods. Attaches easily, is adjustable and offers added protection. Can also be used to hold your line if you prefer to keep it attached and your rod all set-up and ready to go. Available in sizes Small and Large. Fits all Zen rods except the Kyojin (sorry, it's just too big). We recommend you putting your rod cap in a safe place and using this as your everyday tool.
