"PLS laser tools were developed to give contractors the ability to transfer critical layout reference lines and points for any job site task. All PLS laser tools are self-leveling, compact and durable laser alignment tools. Built by contractors for contractors, PLS tools were developed out of necessity by professional carpenters with over 50 years of experience in commercial and residential interior and exterior layout. PLS founders were contractors first before becoming manufacturers of the finest point-to-point and reference line layout tools in the world. All PLS tools are designed and manufactured under strict quality control guidelines. Distribution of PLS laser tools is limited to professional building materials dealers and other laser tool specialists across the country."
