Rotating laser by Laser Reference
The L3 Laser is a leveling and alignment tool for the professional homebuilder or remodeling contractor. It is manually leveled in horizontal mode and manually plumbed in vertical mode. In its horizontal mode, the visible rotating beam provides a planar reference allowing one person to check grade, level-drop ceilings or align fixtures. A fixed plumb beam emitted from the top of the unit is useful for transferring points from floor to ceiling.
