Abstract
A subgrade vault with a latching cover. The vault includes a peripheral wall with an open access port at the top. A peripheral ledge surrounds the access port. A cover to close the access port fits inside it, with a latch assembly inside it and a retractable latch pin disposed to fit in an aperture in the peripheral ledge. The latch pin is retractable by the stabbing motion of a tapered tool against a cam surface on the latch pin. The cover is locked in place merely by pressing down on it.
