Abstract
A plug for an air vent which fits into the top aperture of the air vent prevents cement flowing into the vent when a concrete floor is laid. The vent has a peripheral protrusion and a top flange. The plug protrusion snap fits into a concave groove in the top of the vent aperture. The flange extends upward an outward from the vent top so the laid concrete floor has a slot communicating with the vent and the vent top is installed below the floor and thus cannot be easily damaged by storing and removal of produce.
