KNIPEX Adjustable Wrench: Plastic Dipped, Chrome, 10 in Overall Lg, 1 1/8 in Jaw Capacity

These insulated adjustable wrenches have coated handles to protect from electric shock and reduce the possibility of electrical arcing caused by a short circuit from a noninsulated handle. They come with a screw mechanism located at the bottom of the head that adjusts the jaws for a tight grip on a variety of fastener sizes. The insulation cushions the handle to reduce fatigue and provides a more secure hand grip compared to bare metal handles.
