Sea-Dog 331335-1
Miniature clamshell cover
Low-profile shield for ventilation, wiring or blower-exhaust openings
Identify Sea-Dog Stainless Boat Vents by Shape and MPN
Sea-Dog stainless ventilation covers are not all interchangeable. A low-profile clamshell shield, a midget vent and a flat locker-door grille serve different mounting locations. Use the exact MPN, shape and original screw locations to identify the correct replacement before making a new opening.
Recognize the original cover
Mini clamshell · 331335-1
A low-profile stamped stainless cover that shields vent, wire or blower-exhaust openings where a taller fitting could interfere with deck movement or lines.
Midget series · 331360-1 / 331370-1 / 331375-1
Three sizes of compact stainless vent covers. The large 331375-1 adds a reinforced rim, intended for more exposed service such as small lockers.
Locker-door grille · 331620-1
A stainless ventilation fitting for an interior locker door, helping air move through enclosed storage compartments.
Choose by actual opening
Outside cover dimensions and fastener patterns are not automatically the cutout size. Compare the correct manufacturer drawing and existing opening before drilling.

Examine the vent before reusing it
- Find the exact manufacturer number in the original records, or match the profile and size against the correct product drawing.
- Inspect the flange or rim for bent metal, sharp edges, pitting and damaged or enlarged mounting holes.
- Check any locker-door opening for sound mounting surfaces and signs of trapped moisture.
- Ensure the proposed cover does not restrict required airflow, route water into the vessel or conflict with nearby cable runs.
- Confirm what fasteners or sealing components are actually supplied in the individual listing. Viewing and pickup at UsedRVParts in Kelowna are by appointment.
Different ventilation applications: A stainless cover is not a complete ventilation system. Confirm the opening area, required airflow, mounting surface and any relevant marine safety standard for the intended installation.
