The SKIL Self-Leveling 360-Degree Cross-Line Laser projects a bright, continuous, horizontal line around an entire room, up to 65 ft. in diameter, making it easy to hang pictures at the same precise height, install chair rail molding or a wallpaper accent, and more. In addition to the 360° continuous level line, it can project plumb cross lines to accurately guide a range of DIY projects. The laser level tool automatically levels, and features intuitive indicators that 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 included adjustable tripod makes it a snap to position the laser lines exactly where you want them. And for projects where you might not want your lines to be level or plumb, like specialty paint treatments or diagonal tile work, the SKIL Self-Leveling Cross Line Laser has a locking mode that lets you position the projected lines at any angle you choose.
