The Self Levelling Cross Line Laser Level Kit from Draper is a highly functional laser level, ideal for use where a constant level or repeat level measurements are required. The class 2 laser projects horizontal, vertical, or cross beam lines on surfaces, with automatic self-levelling for ease of use. With a carrying case included, the laser level is easy to move around the work area, and has greater protection from accidental damage. The level comes packed in a sturdy carry case, with a heavy duty adjustable tripod, laser enhancement glasses, and 3x AAA size batteries.
