With the Ryobi RB360GLL cross line laser, achieve precise alignments for all your projects. The green laser lines are up to 4 times more visible than red lasers, with a range of 25 meters. You project a 360° horizontal line and a vertical line, which you can activate individually. The automatic self-leveling stabilizes the laser within 2 to 4 seconds with an accuracy of 0.5 mm/m. This makes the RB360GLL ideal for hanging kitchen cabinets, shelves, or aligning tiles and wallpaper. The laser is delivered in a case and operates on 4 aa batteries.
