The STANLEY CUBIX red beam cross laser level is ideal for DIY and light construction work, including leveling picture rails and hanging cabinets. By projecting bright red vertical and horizontal lines onto flat surfaces, users can easily check whether the object they are installing is level. The innovative self-leveling pendulum ensures accurate laser readings. The effective range of the device is 12 m and the accuracy is +/-4.5 mm at 10 m. The unit is IP50 rated for protection against dust.
