ABSTRACT:
A selectible beam/plane projecting laser is particularly useful for vehicle frame and body alignment. A lens contained in a holder mechanism mounted on a laser projector housing flips into and out of the laser beam path and when in the path, changes the beam to a plane. When used for vehicle frame and body alignment, the plane of the laser generated light allows the operator to spot targets any place in the plane of light and makes easier determination of alignment conditions.
