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. Every contractor has basic alignment tasks to perform on the job site. No project can be completed without layout of the work, installation of material and quality control. Each of these functions is accomplished by determining plumb, level and square reference. PLS lasers provide bright, crisp reference points and lines, for quick and accurate layout. 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.
