Description: |
| The wrench uses a threaded taper to force a gripping surface against the inner face of barrel bung bushes. This grip allows the wrench to install such relatively thin metal shells into wooden barrels. The gripping surface is attached to the body of the wrench by a groove in the upper body, and by a nut at the bottom. |
