Sometimes you just want to be able to stop the flow of your beer or wine. The Large Tubing Clamp provides a better flow for 3/8", 7/16" or 1/2" tubing. If you need to stop the flow of your liquid, simply push on the clamp until the flow stops, and the unit will lock into place. Then unclamp, and you are ready to start flowing again.
Note: Both large and small clamps shown in photo.
