Patent ID: 7340841

Claim:
A slope level for measuring the slope of a surface, the slope level comprising: at least one transparent arced tube, the tube defining an inner space containing a liquid therein and a bubble of gaseous fluid disposed in the inner space within the liquid; a body comprising: a top side and a bottom side, the bottom side defining a first planar measurement surface, a front face and a back face disposed between the top side and the bottom side, the front and back face of the body respectively defining a front and back face of the slope level, and at least one aperture in the body from at least one of the front face or the back face, the aperture corresponding to the arced tube; a measurement template comprising measurement indicia to indicate slope based on the position of the bubble; and a clear cover; wherein the arced tube is embedded in the body and the clear cover is positioned to cover and protect the arced tube; wherein the arced tube has a first end and a second end and the arced tube defines a pinnacle point between the first end and the second end; and wherein the first and second ends of the arced tube are in closer proximity to the first planar measurement surface than the pinnacle point.
