摘要：
A self leveling laser plumb assembly having a battery powered laser unit, a laser unit mounting support, and at least three support legs secured to the bottom of a gimbal ring assembly. The top end of the laser unit mounting support removably receives the laser beam unit. The laser unit mounting support vertically aligns itself by gravity. This allows a beam of light from the laser unit to be directed upwardly to a surface where a predetermined spot can be marked.
