Description: |
| The patent is for a relatively light weight cast all metal wrench handle. The inside of the casting has "ribs" that bear on the main wrench shank. This patent was used for the COES STEEL HANDLE wrench in nominal sizes from 4" through 21". The 6" COES AUTO is a special thin profile version.
The handle on all of these was made with straight lines instead of the slight flare shown in the patent drawings. |
