Description: |
| This socket wrench is designed for the bolts used on demountable rim automobile tires. The side handles give extra leverage for the initial loosening and final tightening, and in between act as "speeders." It was marketed as the Lawrence EasyWay Wrench.
One catalog listing indicates at least three sizes were made corresponding to the bolt sizes used on common brands of demountable rims. |
