With its small size of 150 mm, the pliers wrench fits in any pocket, while also replacing a whole set of spanners - metric and imperial. It grips all widths up to 27 mm or 1 inch, and can be adjusted quickly and directly on the component at the push of a button. The hinge bolt then engages securely, preventing inadvertent adjustment. When under tension, the smooth gripping jaws are parallel to each other in every position, and hold the component accurately and with zero backlash, without damaging edges and sensitive surfaces such as chrome or brass - important during plumbing and heating installation for example.
