Level and level assembly

1. A level device comprising:

a body comprising a first face, an opposing second face, and a perimeter extending between the first face and the opposing second face;

the perimeter comprising a first side, a second side, a third side, and a fourth side, a first reference surface extending along the third side, a second reference surface extending along the fourth side orthogonal to the first reference surface, and a third reference surface between the first and second reference surfaces disposed at a 45-degree angle relative to each of the first and second reference surfaces;

a first bubble vial received in a first recess defined along the first side, the first bubble vial having a first longitudinal axis parallel to the first reference surface; and

a second bubble vial received in a second recess defined along the second side, the second bubble vial having a second longitudinal axis parallel to the second reference surface.

2. The device of claim 1 , wherein at least one of the first and second faces comprises a fourth reference surface.

3. The device of claim 1 further comprising an opening extending through the body from the first face to the opposing second face.

4. The device of claim 3 , wherein the opening is sized to accommodate a finger of a user.

5. The device of claim 1 further comprising a plurality of O-rings disposed between the first bubble vial and a surface of the first side and between the second bubble vial and a surface of the second side.

6. The device of claim 1 further comprising a first magnet recessed within one of the first and second reference surfaces with an outer surface of the first magnet positioned substantial flush with the reference surface.

7. The device of claim 6 further comprising a second magnet recessed within another one of the first and second reference surfaces.

8. The device of claim 6 further comprising a second magnet recessed within one of the first or second faces with an outer surface of the second magnet positioned substantially flush with the first or second face.

9. The device of claim 1 further comprising:

a first magnet recessed within the first reference surface with an outer surface of the first magnet positioned substantially flush with the first reference surface;

a second magnet recessed within the second reference surface with an outer surface of the second magnet positioned substantially flush with the second reference surface; and

a third magnet recessed within the first or second face with an outer surface of the third magnet positioned substantially flush with the first or second face.

10. The device of claim 1 further comprising a fourth reference surface parallel to the third reference surface.

11. A level assembly comprising:

a level comprising:

a body comprising a first face, an opposing second face, and a perimeter extending between the first face and the opposing second face;

the perimeter comprising a first side, a second side, a third side, and a fourth side, a first reference surface extending along the third side, a second reference surface extending along the fourth side orthogonal to the first reference surface;

a first bubble vial received in a first recess defined along the first side, the first bubble vial having a first longitudinal axis parallel to the first reference surface; and

a second bubble vial received in a second recess defined along the second side, the second bubble vial having a second longitudinal axis parallel to the second reference surface; and

a level attachment mechanism embedded in or integrally formed with the body; and

a leveling extension comprising:

a first plate comprising a first extension reference surface;

a second plate comprising a second extension reference surface orthogonal to the first extension reference surface;

an extension attachment mechanism comprised in at least one of the first plate and second plate,

wherein the extension attachment is configured to couple with the level attachment mechanism to releasably couple the level to the leveling extension such that the first extension reference surface is parallel to the first reference surface of the level and the second extension reference surface is parallel to the second reference surface of the level.

12. The level assembly of claim 11 , wherein the level attachment mechanism comprises a first magnet recessed within the second reference surface with an outer surface of the first magnet positioned substantially flush with the second reference surface.

13. The level assembly of claim 12 , wherein the level attachment mechanism comprises a second magnet recessed within the first reference surface with an outer surface of the second magnet positioned substantially flush with the first reference surface.

14. The level assembly of claim 12 , wherein the level attachment mechanism comprises a second magnet recessed within the first or second face with an outer surface of the second magnet positioned substantially flush with the first or second face.

15. The level assembly of claim 11 , wherein the level further comprises a third reference surface between the first and second reference surfaces disposed at a 45-degree angle relative to each of the first and second reference surfaces.

16. The level assembly of claim 11 , wherein the second plate bisects the first plate.

17. The level assembly of claim 11 , wherein the leveling extension consists of the first plate, the second plate, and the extension attachment mechanism.
