In order to meet the increasing demand for professional laser tools, FCL was particularly designed for floor tilers. It offers a timesaving alternative to the traditional chalk-line method. The precise laser-cross generated by two sets of aligned line-lasers enables the craftsman to work directly along the laser axis. Additionally the FCL can be used for facility surveying and construction planning. A combination of clear and appropriate form language, easy handling and the effective application of laser technology makes the FCL a serviceable laser tool.
