Insert a tube through the oval opening into the clamping area, then close the clamp to secure it in place. Use supports, even if there's an empty space between the top clamp and bottom part in the clamping area. Carefully separate all the supports by holding the end of the locking area with one hand or thumb, while prying under the top clamp to pry it up. After that, you may need to sand the area at the end of the clamping area where the clamps meet. Once you've done that, your product is complete.
