Drilled to accept an airlock (#7008 and 7010).
Universal bungs have a longer taper than standard rubber stoppers, for snugger fit and better seal — plus a lip prevents bung from falling into carboy.
This drilled universal bung will work with glass carboys.
Top Diameter: 1.56"
Bottom Diameter: 1.156"

Works just fine.
Needed an urgent order for Christmas and package came within 2 days. Was able to brew with the family during the holidays and utilize our drilled spicket fermentor with the topper.
Everything is working just fine
It barely fit my 3 gallon carboy, right at the narrowest tip. It isn't very tacky so easily comes out. It will probably work better for larger vessels.
