This JLX billet laser is equipped with an ultra-bright green laser (Class II, <1mW) beam which is 400% more visible than red lasers and can be used to extend reference beams over long distances. With five vials, this level accurately measures 0°, 30°, 45° and 90° while the Multi-Pitch vial reads in 1/8" increments for measuring drainage slope. It also features a solid machined aluminum billet frame with protective anodized finish for durability. Powerful GripTight rare earth magnets hold to flat or round ferrous metal surfaces for convenient hands-free use.
