Abstract
A level for indicating the orientation of each of a surface, a first electrical device, or a second electrical device, the level including a first planar surface, a second planar surface, a web, and a vial. The web is coupled to the first planar surface and the second planar surface such that the first planar surface is spaced apart from and is parallel to the second planar surface. The vial has a long axis and contains a liquid and a gas bubble and is coupled to the web such that the long axis is substantially parallel to the first planar surface. A first perimeter is formed as part of the web, shaped substantially the same as a portion of the first electrical device, and sized to engage the portion of the first electrical device such that the vial is operable to indicate the orientation of the first electrical device.
