Description: |
| Two open ends, with opposite ends tapered, connected at the center by a pivot.
Intended as a plumber's wrench for fittings of various sizes and types; when expanded as an "X" and used with a supplemental rod, would work in interior of sink and bath drains, or other fittings that have interior lugs.
Markings on known examples imply Stoffel was producing these at Tulsa; documentation has not been found as of Sept. 2025. |
