Abstract: On a conventional pipe wrench, an L-shaped lever arm has the short bisected arm segment cooperatively disposed over and secured by a fixed pivot to a linear extention of the threaded section of the adjustable pipe jaw. A free pivot disposed at the terminus of the bisected arm secures a roller between and in the short bisected arm segment. The L-shaped lever arm and pivoted roller are adaptively sized and shaped to provide a lock means for the pipe jaw when the lever handle is pressed down against the pipe wrench handle, locking the roller against the wrench handle by compressing the roller in detent against the wrench handle.
