Johnson's builder's transit level system includes everything you need to set up level points and check elevations on your construction site. Easy to assemble, easy to use and lightweight, the included builder's transit level consists of a leveling vial attached to a telescope. The leveling vial is accessible to ±45° on a vertical arc, with graduations to single degrees and reads by a Vernier scale to 15 arc minutes for maximum precision. Its horizontal tangent screw and vertical lock with tangent screw give you precise movement control so your readings are accurate every time. Johnson's builder's transit level is extremely user-friendly - its built-in sunshade gives you clear sighting, and the large leveling screws are effortless to use. Every transit level requires a tripod, and the contractor grade aluminum tripod included here is lightweight and durable, for easy and dependable use. This level system includes a 13' aluminum graduated grade rod so that determining differences in elevation is quick and easy. Includes a hard-shell carrying case.
