Replacement Instructions : 

1. Open Clamp
2. Turn the clamp counterclockwise to unscrew the current nut.
3. Apply some finger pressure to keep the nut from turning as you unscrew it.
4. Position a new nut in the hole where the paddle clamp is located, making sure the side with the colored seal is facing outward.
5. Insert the screw portion of the clamp into the hole and nut.
6. Tighten the clamp clockwise.
7. When the clamp is tight enough, close it to make sure the top of your paddle doesn't move. Voila!
8. If it is too tight, loosen it by turning it counterclockwise.
