If the ports on your Straight Line Sumo or Big Bag wakeboard ballast bags leak slightly when the bag is completely full these retrofit clamp kits will solve the problem.

Easy to Install:

1. Step 1: Loosen the screw to open the locking ring
2. Step 2: Install clamp on port below "lip"
3. Step 3: Tighten to secure the connection

FYI: If the valve cap is marked with "SUMO" Logo the locking ring is not needed for a secure connection.
