Carlyle professional combination wrenches can be considered among the highest quality wrenches available on the market today, according to the company. Each combination wrench features chrome-vanadium, high-alloy steel construction, produced using a hot forging process with extra emphasis on special heat treatment to provide maximum strength and durability. These long panel wrenches include a non-slip open end and full-mirror, polished chrome plating. The open end comes non-chamfered on one side to provide additional gripping power on partially rounded fasteners. It is available exclusively through NAPA.
