1. A laser level comprising:
a housing;
a laser generator positioned within the housing and emitting a laser projection plane;
a base rigidly coupled to the housing;
a cage rigidly coupled to the base, the cage comprising:
an aperture in an upper portion of the cage; and
a plurality of legs that together define a plurality of side windows, wherein the laser generator is configured to direct a laser projection out of the plurality of side windows; and
a masking component moveable over each of the plurality of side windows;
wherein each of the masking components are moveable between a first position in which the masking component does not block the laser projection plane through the associated side window and a second position in which the masking component blocks the laser projection plane through the associated side window.
