Abstract
An angle finder for large diameter ducts and piping. It consists of a pair of legs having front and back sides, and top and bottom ends. The top ends are pivotally connected, thereby forming an inverted adjustable “V.” There also is provided a moveable center pointer having a top and a bottom mounted on the top end of the legs so as to bisect the “V” formed by the legs. Finally, there is a direct reading angle finder, preferably used in conjunction with a laser, mounted near the bottom of the moveable center pointer.
