Abstract: An angle indicator is provided for use with a pipe bender and is adapted to be removably mounted to a handle of a pipe bender. The angle indicator includes a plate; a first wheel rotatably mounted to the plate and including a plurality of angle indicating marks evenly spaced about a periphery of the first wheel; a second wheel rotatably mounted to the plate concentrically with the first wheel; the second wheel being smaller in diameter than the first wheel and including a mark at a periphery of the second wheel, the mark being selectively alignable with one of the angle indicating marks of said first wheel; a bubble level mounted on the second wheel; a first lock to hold the first wheel in a desired rotational position; and a second lock to hold the second wheel in a desired rotational position. The use of two wheels allows for zeroing of the angle indicator and dialing in of the desired angle.
