Abstract
A level is provided with a top-reading feature, allowing a vial to be viewed through the upper flange of the level. A magnifying element is disposed between the vial and an opening formed in the upper flange, to magnify the vial when it observed from the top of the level. The magnifying element is preferably formed integrally with a transparent lens, which is retained between a vial cover and a side of the web of the level frame. Complementary structure is provided on the lens on the opposite side of the web, for sealing the internal cavity defined by the vial covers, in combination with the lenses, to prevent entry of dirt or other foreign material into the cavity.
