With a ½-in. square opening on the side, this pipe wrench head adapter can be attached to a breaker bar, torque wrench or any tool with a ½-in. male drive. Because the tool is just a wrench head, workers can easily grab it from different angles, useful when working in tight spots. When used with a ratchet, the tool’s stop bar prevents unwanted ratcheting during repositioning. Teeth can be replaced in the field.
