Abstract: First and second handles of a tool are spring biased to pivot into a closed position in which mounting end portions of the handles abut each other. A band has a first end attached to the mounting end portion of the first handle and extends therefrom to form a loop. The opposite end of the band is slidably received through passages through the mounting end portions of the handles. A series of openings through the band correspond to various predetermined use diameters. A pin extending into the passage in the second handle engages one of the openings corresponding to a selected use diameter. The gripping end portions of the handles opposite the mounting end portions are squeezed together to increase the effective diameter of the band loop and allow the loop to be placed around parts to be aligned.
