Stanley’s Cubix, model STHT77340, is a cross-line laser ideal for light residential con-struction from leveling chair rails to hanging cabinets. It projects bright horizontal and vertical lines onto flat surfaces for easy leveling of a variety of projects. In auto-leveling mode, it automatically levels using an internal pendulum. If the angle of the tool exceeds 5° from level, the laser will shut off and an indicator will light up signaling it has exceeded the 5° in which it is able to self-level. It has up to a 40’ range with an accuracy of +/- 5/16”.PM0215_Products_laser-meters_Stanley-Cubix_300.jpg
