General description The Bosch GCL 2-15 Professional Combi Laser is a compact and versatile self-levelling tool designed for all short-distance levelling applications up to 15 m. It projects both horizontal and vertical laser lines along with two centred plumb points, making it ideal for various tasks such as mounting shelves, installing drainage pipes, and laying floors. The highly visible laser lines can be easily aligned in a 360° circumference around the fixed plumb points without repositioning the tool, thanks to the RM 1 Professional rotating multi-functional mount.
