Description: |
| Combination nut and pipe wrench. A spring-loaded pivoting insert in the inner jaw has smooth and toothed sections for nuts and pipe. The outer movable jaw slides over ribs on the body. The lower portion of the movable jaw has hook-like teeth inside. These teeth engage notches cut in a shank extending from the handle to hold adjustment. The shank has a pin to hold it in place, and which limits the amount of rotation. In use, turning the handle to disengage the shank notches from the teeth in the movable jaw allows the jaw to slide to set the size adjustment.
Altogether way too complex and fragile to be practical. |
