The louvered blade pattern deflects rain and spray away from the opening, making it a practical choice for ventilating enclosed spaces that need airflow without exposing the interior to the elements.\u003c\/p\u003e\u003cp\u003eIt is stamped from corrosion resistant 304 stainless steel, giving it long-term durability in a marine environment where fresh water, salt spray, and UV exposure quickly degrade lesser materials. The vent has a net vent area of 2.02 square inches, allowing meaningful airflow through a relatively compact opening. It installs with four #6 flat head fasteners (not included), and requires a mounting hole of 3-1\/2 inches to accept the vent body.\u003c\/p\u003e\u003cp\u003eThis is a hardware-only vent with no moving parts, making it a simple, low-maintenance option anywhere a fixed, weather-resistant air vent is needed on a boat, deck box, console, or hatch.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 331425-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Round Louvered Vent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Stamped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Size:\u003c\/strong\u003e 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hole Size:\u003c\/strong\u003e 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 4-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Area:\u003c\/strong\u003e 2.02 square inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e #6 flat head (fasteners not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.148 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 035514331128\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis is a universal round louvered vent; it is not model-specific and fits any application with a matching 3-1\/2 inch mounting hole.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size mounting hole does the Sea-Dog 331425-1 vent require?\u003c\/strong\u003e The Sea-Dog 331425-1 round louvered vent requires a 3-1\/2 inch mounting hole to accept the vent body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the overall diameter of this vent?\u003c\/strong\u003e The overall size of the 331425-1 louvered vent is 5 inches, with an outer diameter of 4-1\/2 inches at the flange.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 331425-1 vent made from?\u003c\/strong\u003e It is stamped from corrosion resistant 304 stainless steel, which resists rust and pitting in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sea-Dog 331425-1 vent come with mounting fasteners?\u003c\/strong\u003e No, fasteners are not included.
