Abstract: A level comprising a level body and a bubble vial mounted on the level body. The bubble vial includes a bubble vial body comprising a clear material and an internal cavity containing a liquid. A top opening in the level body that interrupts at least a portion of a top wall to accommodate the bubble vial. An internal support structure disposed within the tubular configuration of the level body and spanning longitudinally along the level body so as to be disposed on both sides of the top opening to provide structural support to the level body in the vicinity of the top opening. A carrier positioned beneath the bubble vial and between the internal support structure and the bubble vial. The bubble vial body has a length that is less than a length of the top opening in the top wall of the level body.

Abstract: A composite level and a method to manufacture the composite level are provided. A composite level can have three layers of material. A first layer comprises a glass-mat material, a second layer comprises carbon fiber, and a third layer comprises a glass fabric material. A composite level can also have only two layers of material. At least one bubble vial is mounted on the level body. The method to manufacture the carbon fiber composite level comprises a pultrusion process wherein a fiber glass material and carbon fiber are saturated with resin and molded into a final shape.
