Various laser level designs including the ability to physically/mechanically mask light emitted from the laser level are shown. In one example, the laser level includes physical barriers that can be moved between open and closed positions to selectively block or mask a desired portion of the projected laser plane.

Rotary laser with mechanical mask

A level includes a frame having a top planar surface, a bottom planar surface, and a web coupling the top planar surface to the bottom planar surface. The top planar surface and the bottom planar surface are parallel. The level further includes a vial supported by the frame. The vial has a longitudinal axis passing through a center of the vial and a body defining an interior containing a liquid and an indicator bubble. The level further includes a plurality of LEDs. Each of the LEDs has a light emitting point, and each of the plurality of LEDs is positioned adjacent an end of the vial and is oriented such that the light emitting point is positioned within the interior of the body of the vial.

Level

A level includes a frame supporting a plurality of vials and having an aperture disposed on an end of the level. The level also includes an end cap assembly detachably coupled to the end of the frame. The end cap assembly includes an end cap and a retainer. A portion of the end cap is received in the aperture and is maintained in engagement with the frame by the retainer.

Level including removable end caps

A tool, such as a level, including one or more magnetic coupling device is provided. The magnetic coupling device may be a magnetic circuit including metal components surrounding a magnet, such as a permanent rare-earth magnet.
