Since 1923, RIDGID has remained the symbol of certainty to dedicated professionals of the expert trades. We at the Ridge Tool Company take this heritage seriously. This is why every tool that bears the RIDGID brand is engineered to the same high standards of quality, strength, and endurance as was that first heavy-duty pipe wrench more than 80 years ago. The Ridgid 27023 One Stop Wrench is two wrenches in one. This wrench has a smaller wrench placed inside the body of a larger wrench. Why have two wrenches add weight to your tool box when you really only need one. It provides the exact size wrench you need to install angle stops and compression couplings.
