A level and a method of forming such a level are disclosed. The level comprises a body having a measuring surface and a recess, a vial positioned in the recess at an angular relationship to the measuring surface, and a ring member enclosing the vial within the recess, the ring member engaging the vial and the body and fastened to the body, the ring member having a beveled edge forming a funnel-shaped surface defining slope lines, the slope lines intersecting the vial, whereby the vial is protected by the level and ring member while visibility of the vial is enhanced. The method comprises providing a level with a recess and a measuring surface, positioning the vial in the recess at an angular relationship to the measuring surface, and enclosing the vial within the recess with a ring member, the ring member having beveled edges forming a funnel-shaped surface.
