SELF-LEVELING PENTA LASER BEAM DEVICE

摘要

A multi-beam tool is disclosed which can perform square, plumb, and level function which may be required in a construction environment. The tool can generate in a preferred embodiment up to five orthogonal beams with two beams being plumb and three beams being leveled. The tool includes in a preferred arrangement a self-leveling pendulum (80) to which a laser (4) and quad-mirror arrangement (8a-8d) is secured.
