The SKIL Self-Leveling Red Cross Line Laser Level is a compact tool that makes it simple to align multiple pictures, shelves, or cabinets and install banisters, trim, and more. Its bright red horizontal and vertical lines have a laser distance up to 50 ft. The tool automatically levels, and intuitive indicators let you know when your lines aren't level. The integrated, rechargeable Lithium-Ion battery has a micro-USB port for charge-and-go convenience, plus green, yellow, and red LED indicators to let you know the current level of charge. The multifunctional clamp can be attached to the top or the bottom of the tool for easy positioning on a ladder, table, and lots of other surfaces. And for projects where you might not want your lines to be level or plumb, like specialty paint treatments, the SKIL Self-Leveling Cross Line Laser has a locking mode that lets you position the projected lines at any angle you choose.
