Marinco® Ventilation Installation Systems Snap-In Deck Plate Installation The 12V vent, 12V combo vent and cowl vents use the Marinco Snap-In deck plate system. The snap-in system allows the easy exchange of any snap-in part for upgrading or convenience, as well as the use of a snap-in cover that completely seals the deck plate making it water tight. Direct-To-Deck Installation The Day/Night Plus, MiniVent 1000 and AirVent 500 are designed to be installed directly to the deck without the requirement for a deck plate. All of these vent systems have built-in shutoff dampers that operate from below. TECH TIP Deck Plate Deck Plastic Interior Trim Ring
