Bosch Professional GCL 2-50 G Combination Laser with RM ​10 Mount

The Bosch Professional GCL 2-50 G Combination Laser with RM 10 Mount is an alignment and levelling tool designed for interior installation and construction tasks. It projects two green laser lines alongside two plumb points to establish horizontal and vertical references or transfer points across a workspace. The unit has a maximum working range of 15 m, extending to 50 m when paired with a compatible laser receiver. A self-levelling mechanism compensates for uneven surfaces and provides a levelling accuracy of 0.3 mm/m.

The device has an IP64-rated housing that resists dust and splashing water for reliable operation on job sites. Power is supplied by four LR6 (AA) batteries, which are included in the package. For positioning flexibility, the bottom of the laser integrates a 1/4-inch tripod thread. Bosch includes an RM 10 Professional rotating mount equipped with strong magnets, allowing secure attachment to metal surfaces. A laser target card is also provided to assist with beam visibility over longer distances. Recessed lenses and rubber protection around the exterior shield the internal components from impact.
