The pipe wrench key eliminates the need for sets of metric and imperial wrenches. The smooth jaws ensure damage-free installation of chrome fittings by acting directly on the chrome. It is also excellent for gripping, holding, pressing, and bending workpieces. The zero-play bite pressure prevents damage to the edges of sensitive components. Quick adjustment is achieved by pressing a button directly on the workpiece, without unintended shifts of the gripping jaws and without slippage of the joint. Its design allows for flexible adjustment of all widths up to the specified maximum size. The ratchet principle enables fast and easy tightening and loosening of all screwed connections.
