ABSTRACT:
A bending level tool has a body with longitudinal axis defining a handle at the rear and thereof and axially aligned first level vial at the forward end, with a perpendicularly aligned second level vial attached to the body at an intermediate shank. A pair of spaced tines forming an attachment fork extend normally to the plane established by the axes of the two vials, with one fork flush with the forward end of the first vial and the second tine attached to the shank at the forward face of the second vial, and a screw attached to one of the tines for clamping a pipe wall against the opposite tine. The length and width of various functional parts of the bending level are of predetermined small increment dimensions, preferably multiples of one-fourth inch, permitting ready measurement of pipe diameters and the like, and the angular relations between parts of the level permit square measurement.
