Sea-Dog Stainless Steel Louver Vent 12-7/8 x 4-1/2 in
Sea-Dog Stainless Steel Louver Vent 12-7/8 x 4-1/2 in — Product description
The Sea-Dog stainless steel louver vent keeps air moving through the spaces below your deck without letting spray or rain follow it in. At 12-7/8 inches long and 4-1/2 inches wide, it's a clean, corrosion-resistant fix for stale lockers, engine boxes, and cabins. Five angled louvers do the work quietly.
Stale air is one of those problems you don't notice until you open a locker and get hit with that damp, closed-up smell. This Sea-Dog louver vent fixes it. It's a stainless steel ventilator with five angled slots that let air flow in and out of an enclosed space while the downward pitch of each louver keeps rain and deck spray from riding along with it. Passive ventilation, no moving parts, nothing to wire in.
The panel measures 12-7/8 inches long by 4-1/2 inches wide, so it covers a good amount of area without eating up a whole bulkhead. Stainless steel is the right call for a part that lives out in salt air. It won't rust streaks down your gelcoat the way a cheaper vent will, and it keeps that bright finish for years. You get one vent per package.
Where does it go? Anywhere trapped air causes trouble. Engine compartments that run hot. Anchor lockers that never seem to dry out. Cabins, heads, and battery boxes that need a steady exchange of air to stay fresh and keep condensation down. Boaters also use these on livewells and storage compartments where moisture builds up. Even a boat that sits on a trailer through the off-season breathes easier with a vent that lets a closed hull dry out. Cut the opening to match, drop it in, and fasten it through the mounting holes. It's a straightforward afternoon job for most owners.
Because it's a fixed louver, there's no cover to close and nothing that'll seize up on you mid-season. That's the trade. You get constant airflow and a part that just works, but it isn't a sealed vent you can shut down in heavy weather. For most below-deck spaces that need to breathe, that's exactly what you want. If you're replacing a tired plastic vent or adding ventilation to a compartment that's been running muggy, this is a clean, honest upgrade that'll outlast the boat around it.

Frequently asked questions
What is this louver vent used for?
It ventilates enclosed spaces below deck. Boaters install it on engine compartments, anchor lockers, cabins, heads, battery boxes, and storage compartments to keep air moving and cut down on trapped moisture and condensation.
What size is the vent?
The panel is 12-7/8 inches long by 4-1/2 inches wide with five louvered slots. Cut your opening to match before mounting.
Is it really stainless steel?
Yes. It's built from stainless steel, so it resists salt-air corrosion and holds its bright finish without rusting streaks onto the surrounding surface.
Will it keep water out?
The louvers are angled downward to shed rain and deck spray while air still flows through. It's a passive vent, not a sealable one, so it isn't meant to close off a space in heavy weather.
How do I install it?
Cut an opening to fit the vent, set it in place, and fasten it through the mounting holes. It's a straightforward job for most owners with basic tools.
How many vents come in the package?
One. This part number is sold as a single vent.
