A vent assembly has a vent cover and sliding air flow regulator for controlling the flow of air through the vent cover. Plural sets of unique couplers may be used to interconnect the air flow regulator and vent cover for relative sliding motion. Desirably, two such couplers are provided at each end of the assembly with an associated one of such couplers being adjacent to each of the corners of the assembly in the event a rectangular assembly is provided.
