ABSTRACT:
A level and protractor tool (100) includes a body (102) with three sections. The first section (106) includes a spring clip (108) mounted on the body. The spring clip is adapted to be attached to an item that is to be bent or otherwise measured with the level and protractor tool (FIG.6). The second section (128) is contiguous with the first section. The second section includes a mounting pin (132) defining a rotational axis for both a pointer (134) and a degree wheel (136) having a pendulum weight (306). The degree wheel and the pointer are positioned with respect to the mounting pin for rotational movement about the mounting pin independent of one another. The third section (142) includes a bubble level or spirit vial (144) and is attached perpendicularly to the second section and parallel to the mounting pin. When the spring clip is attached to an article that is to be bent, the degree wheel and pointer provide a scale for determining the angle of the bend, and the bubble level vial gauges lateral displacement.
