S-2750 Stopper - Stopper Sizer

The stopper sizer easily determines the correct size cork or stopper needed for any flask, bottle, etc. Just insert this thin triangular gauge into the vessel and the correct stopper size is read off the line at the top of the neck. Two scales are provided: one for rubber and Vinyl stoppers and the other for corks. On the back side is a circular scale for sizing tubing outside diameters between 4 and 52mm.
