Abstract: Adjustable size saddle type single loop belt wrenches are disclosed which do not bite sharply at a corner or the like into the side of an object comprising a flexible, non-metallic belt, both ends of which are free, but one end being equipped with a clasp-engaging stop. At least two ends of the belt pass in substantially parallel relation through the clasp which is also eyesight, in conjunction with a turning tool, to bias the belt circularly around an object to be turned. The rotation of the clasp with the tool is along an axis generally parallel to but offset from the axis of the object. Only a small angle of rotation is required whereby the stop engages the clasp and a flat or continuous surface of the clasp imposes a distributed load across the belt onto the object to be turned.
