The jaw opening varies in 6 steps with irregular pitches to accommodate pipe standards, yet the handle opening remains mostly consistent regardless of workpiece size. You’ll also find a safety design with a stopper to prevent your hands from getting caught in the handle. This tool works with nuts up to 41mm wide (M27), pipes/round rods up to φ50 mm, and 3/8 stud bolts. Plus, it boasts a lightweight design at only 280g, approximately 30g lighter than our conventional models, and a new profile that won’t damage nut heads. It’s versatile for piping, plumbing tasks like handling tap water faucets, tightening/removing nuts and bolts, and even twisting, bending, and tensioning wires.
