The KR Series Kayak Paddle from Caviness - plastic-clad, super strong, aluminum shaft that extends fully into the blade's length for internal reinforcement, and also has pre-installed drip rings. With our unique take-down coupling feature, our Kayak Paddles can have the blades run parallel (in-line) or they can be feathered 90 degrees by simply depressing the spring-loaded button and turning the shaft 1/4 turn. It's like having two kayak paddles for the price of one.Specifications and Features:Fully plastic-clad aluminum shaftPre-installed drip ringsCaviness take-down coupling
