The Bosch PLL 360 Premium projects a clear and accurate 360-degree laser line. That makes this tool the perfect aid for applying decorative trims, building an elevation, or lowering a ceiling. Each laser line can be fixed with a press of a button. That way, you can, for instance, align paintings parallel to the stairs. The PLL 360 has a simple control panel and comes with a universal holder and a tripod, so you can always easily set it to the right height.
