What is the difference between a NC74S trim and a NC74VS trim !?

The standard trim has a much larger door opening than the vented trim which has louvers at either end. If the standard trim is supplied with 400 or 600a interiors , there would be large gaps in the interior and it would seem like deadfront pieces are missing. But that is not the case.
