Abstract: The present invention relates to a one-piece structure tool for squaring and leveling pipes and flanges, and verifying the measurements of the same. The tool is designed as both a measurement tool and a leveling tool. The tool comprises two graduated arms connected in a V-shape (i.e., acute angle), each arm has s horizontal vial(s) and vertical vial(s) for maintaining horizontal and vertical level of the flange. The graduations are used for verifying measurement of flanges and other piping elements. In various embodiments, the arms have a length of one, two, or four feet. The tool is designed to save time, effort, and money when squaring, leveling and measuring materials such as pipe flanges, pipe fittings, and pipe elements.
