GreenBrite® Dual Slope Rotary Laser Kit

MODEL #:  JRT300-GNHV-K

Elevate your job site precision with our advanced GreenBrite® Rotary Laser, designed to meet the demands of your interior applications. The green beam, an impressive 400% more visible than red, ensures unparalleled visibility. With a 4000-foot range, this laser level provides maximum coverage for your job site. Built tough with an IP67 rating, it can withstand the harshest environments, offering durability in challenging conditions. The impact resistance of up to 6 feet protects against tips and drops, ensuring longevity on the jobsite. With five rotational speeds, a 400-foot remote range, and a detector (bracket not included) for one person operation, this laser level maximizes efficiency. The electronically-controlled dual slope operation allows you to perform slopes up to 5 degrees in both the x and y axis, catering to versatile job site requirements. The lithium-ion rechargeable batteries boast an impressive 21+ hours of runtime, keeping you powered throughout the day. With four angle scan modes and visual and audible alarms, this laser level is your ultimate companion for precision and safety.
