    摘要: A shielded locking system for securely closing a lid on an enclosure, such as a grade level utility vault, including an L-bolt connected to a spring-biased slide member positioned on the underside of the lid that rotates in a slotted housing that securely retains the L-bolt under the lid, the slide member engaging an abutment on the inside of the enclosure when the lid is forced down over an opening in the enclosure by downward force on the lid which progressively causes the latch to retract against the spring-bias from contact with the abutment and then snaps the latch into a spring-biased locking position under the abutment, and a non-conductive cover positioned over and connected to the locking system to shield the L-bolt from electrical conductivity from within the enclosure.

    摘要: A fiber reinforced polymer material lid or cover for a utility vault made from an unsaturated polyester thermosetting resin matrix, glass fiber reinforcement, an inorganic filler and an ultraviolet inhibitor. The lid or cover has a flat textured upper surface having a plurality of bosses having different heights extending above the upper surface and a bottom surface having an outer perimeter rim with a recessed interior cavity having a number of continuous support ribs extending through the recessed interior cavity from opposite sides of the outer perimeter of the rim to transfer load placed on the lid or cover and minimize deflection under the load to the outer perimeter rim.
