Use the Harmony FeatherLok clamp to replace a broken or damaged ferrule on Harmony paddles with the Featherlok ferrule. This clamp only works on paddles that have an existing Featherlok ferrule and a fiberglass shaft. You will need some fiberglass resin or urethane adhesive to attach the ferrule to the shaft, sold separately.
Broke the clamp handle a few years ago by accidentally leaving it in the open position and placing camping gear on top of it in the car. Was able to use the stump until I lost the screw. Hoped to get just the handle replaced, but ended up having to buy the ferrule. Worth the price to save a favorite paddle. Works like a charm again. I will be more careful storing the paddle in the future as it seems that this ferrule may be discontinued by Harmony.
