These high quality, heavy duty industrial 1200mm pipe wrenches are used for turning pipes & fittings. The adjustable jaw allow it to lock in, with any forward pressure on the handle pulling the jaws tighter together. The angle of the teeth also help against slipping as they are angled so they dig into the pipe as it is turned. These pipe wrenches feature a carbon steel Jaw-drop with a body of ductile cast iron. Clamp size 110mm.
