The Oceanus Rope Extension runs between the webbing attachment on the board and the stainless steel clip of the reel. The rope keeps you connected to the reel without tension while you're riding. If yours is looking worn out, it may be time to replace it. The Rope Extension is approximately 30 inches long, 1/4-inch diameter rope that's doubled over and stitched. Comes with rope, webbing attachment, and washer.
