US Patent 10006768 Laser level

A laser level including a housing. A laser generator assembly is housed in the housing and generates a laser beam. A projector projects the beam from the laser generator outside of the housing onto a target surface. The laser is a rotary laser and the projector rotates to rotate projection of the beam. The laser level also includes protective arms extending from the housing, the protective arms blocking projection of the beam along part of its path as the projector rotates. A width of the beam is at least twenty percent greater than a width of the leg where the beam contacts the leg.
