Description: |
| Screw-adjust, with a notch cut through the adjusting screw to allow the reversible adjustable jaw to quickly adjust for size, or be slid out and reversed to switch between use as a pipe or nut wrench. The handle and fixed jaw portion are formed of a pair of stampings.
The reversible movable jaw that works with nut or pipe jaw surfaces on the fixed jaw is similar to the May, 1913 CARLL patent (no. 1,060,891). |
