Patent attributes
A lid for a utility enclosure having a front end, a rear end, a right side, a left side, a top lid portion, and a bottom, defining an interior. Large reinforcement ribs are on an interior surface of the top lid portion and form a lattice-type structure. Small reinforcement ribs are mounted in spaces formed by the lattice type structure. The lid is made of glass fiber-reinforced polypropylene and metal bars or rebar are embedded in the large reinforcement ribs. The metal bars are positioned near a bottom of the large reinforcement ribs and spaced above the bottom. The physical structure of the lid and the lid's composition, consisting essentially of glass fiber-reinforced polypropylene, are constructed so that the lid withstands up to 33,750 pounds of force without breaking or being deformed.
