ABSTRACT:
A level assembly includes a main level with a base wall, end supports at opposite ends of the base wall and at least one intermediate support extending from the base wall at a location between the end supports. Bubble tubes may be mounted in the end supports and/or the intermediate support of the main level. At least first and second auxiliary levels are releasably mounted to the base wall of the main level and can be used independently of the main level. Alternatively, the main level can be used with the auxiliary levels in place and in certain embodiment can be used while the auxiliary levels are separated from the main level.
