Abstract:
Detailed herein is a level device having a body having a first face, an opposing second face, and a perimeter extending between the first and second faces. The perimeter includes first, second, third, and fourth sides, where a first reference surface extends along the third side and a second reference surface extends along the fourth side orthogonal to the first reference surface. A third reference surface may be 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 having a first longitudinal axis parallel to the first reference surface is received in a first recess defined along the first side, and a second bubble vial having a second longitudinal axis parallel to the second reference surface is received in a second recess defined along the second side.
