Ideal for hanging pictures, shelves, wall coverings, and more, the Laser Level 30 from STRAIT-LINE offers quick and easy precision leveling in almost any size room. The LL30 rotates 360-Degree for optimal versatility and less transport and setup. The tool emits a vivid, 15-Feet laser beam accurate within +/- 3/16-Inch, and can be aimed in both directions for 30-Feet of coverage. Dual bubble vials allow for both horizontal and vertical layout. The laser mounts easily to any surface with 3M Command Strips (included), which leave surfaces unscathed when removed. A lightweight and compact design allows for easy storage.
