Description: |
A large adjusting sleeve with internal teeth engages teeth on the shank of the movable jaw. The wrench is comprised of only three pieces. The bearing surface between the movable jaw and handle is slightly convex and the adjusting sleeve fits loose enough to allow the movable jaw to rock slightly in relation to the handle. Hollands Mfg. Co. of Erie, PA marketed this as the Keystone Pipe Wrench. |
