Description: |
| Screw adjust hook jaw, and a flat bearing face set at an angle. One ad indicated the angle facilitated work on "octagon" nuts and fittings - the STAR COUPLING for lead and iron pipe had octagon rather than hexagon flats.
Announced as a "new product" in August 1895 with advertising starting in Sept. 1895. |
