4-Inch 316 Stainless Steel Round Marine Louver Vent - Mirror Polished
Improve your boat's ventilation setup with this 4-inch round marine louver vent, made from 316 stainless steel with a high-gloss mirror-polished finish. Designed for surface mounting on compatible marine ventilation openings, this round stainless steel boat vent combines a slotted louver design with a clean, polished appearance for boat interiors and exterior applications where the vent is suitable.
The 316 stainless steel construction offers corrosion resistance for marine environments, while the round louvered face provides a practical solution for ventilation installations on compatible boat surfaces. Three mounting holes around the outer edge allow the vent to be secured with suitable fasteners.

Applications
This 316 stainless steel round boat vent may be suitable for:
- Marine ventilation openings on compatible boat surfaces
- Boat cabin and compartment ventilation installations
- Replacement of an existing round louver vent with matching dimensions
- Marine hardware projects requiring a polished stainless steel vent cover
Compatibility depends on the installation location, ventilation requirements, available space and mounting dimensions. Please verify these details before purchasing.
Installation Information
- Measure the available mounting surface and confirm the vent's overall dimensions.
- Check the required ventilation opening and ensure the vent design is suitable for the intended application.
- Align the three mounting holes with the mounting surface.
- Select compatible 3 mm bolts or rivets and appropriate sealing materials for the installation.
- Secure the vent without overtightening the fasteners, and verify that the installation is stable.
Fasteners are not included. The correct fastener type and length depend on the mounting material and thickness.
Care and Maintenance
Rinse the stainless steel vent with fresh water after exposure to salt spray or marine deposits. Clean it with a soft cloth and a suitable stainless steel cleaner, following the cleaner manufacturer's instructions. Avoid abrasive materials that may scratch the mirror-polished finish.
Although 316 stainless steel offers good corrosion resistance, actual performance depends on exposure conditions, installation, maintenance and contact with other materials.
Frequently Asked Questions
Is this a 4-inch stainless steel boat vent?
This product is listed as a nominal 4-inch round marine louver vent. Check the product dimension drawing for the actual outside diameter, opening requirements and mounting-hole positions before ordering.
What material is used for this marine vent?
The vent is made from 316 stainless steel. This grade is commonly used for marine hardware because of its corrosion resistance. Regular cleaning is still recommended, especially in saltwater environments.
How many mounting holes does the vent have?
The vent has three mounting holes, each measuring 3.5 mm in diameter. Suitable 3 mm bolts or rivets may be used if they fit the mounting surface and installation requirements.
Are mounting bolts or rivets included?
No. Mounting fasteners are not included. Choose fasteners that are compatible with the mounting material, thickness and marine installation conditions.
Can this round louver vent replace my existing boat vent?
It may be suitable if the existing vent has compatible outside dimensions, opening requirements, mounting-hole positions and installation depth. Compare the product drawing with your existing vent before ordering.
Is the mirror-polished finish suitable for marine use?
The mirror-polished finish provides a bright, reflective appearance suitable for marine hardware applications. The 316 stainless steel construction provides corrosion resistance, but no stainless steel finish is completely immune to staining or corrosion under all conditions.
Can this vent be used for every type of boat ventilation?
Not necessarily. Confirm that the vent's dimensions, louver design and airflow requirements suit the intended location. Do not assume it is suitable for engine exhaust, fuel-system ventilation or other specialized applications without confirming the manufacturer's specifications and applicable requirements.
Before You Order
Please review the product dimensions and mounting requirements to ensure compatibility with your boat. If you are replacing an existing vent, compare the mounting-hole layout and opening size before purchase.
