Description: |
Quick adjust action, with paired ratchet dogs in the movable jaw. The paired sets of rack teeth are "half a step apart" which doubles the number of adjustment stops for the wrench. The rack teeth are on either side of a spring which provides sufficient friction to keep the movable jaw open unless intentionally moved. |
