A locking system for closing and locking a lid on an enclosure such as a grade level enclosure. The locking system includes a latch formed on an edge of a lid of the enclosure. The latch includes a bolt recess on an upper face of the lid which opens into a slotted wall structure that forms a passage below the lid. The bolt recess has a slotted opening which receives an L-bolt that extends down into a hollow interior of the slotted wall structure. A right angle leg on the L-bolt protrudes below the slotted wall structure when a fastener head atop the L-bolt rests in the bolt recess. The fastener head of the bolt in its at-rest position in the bolt recess provides access for rotating the L-bolt (and its right angle leg) with a tool that fits into the bolt recess to engage the fastener head. The bottom leg of the L-bolt, when rotated to its locked position, protrudes under a locking surface inside the enclosure. This releasably locks the lid to the enclosure.
