Abstract
A universal lid closure for underground landscape and other utility access boxes uses flexible tongues depending from the underside of the lid and adapted to engage the interior of the access box, which box may have any one of various constructions. In one embodiment, the tongues have a plurality of diametrically opposed pairs of locking detents, each pair defining a different vertical position, to engage an annular locking shoulder on the interior of the box to secure the lid in the closed position.
