This plastic ventilation grille measuring 124 x 112 mm is designed to introduce fresh air into the interior spaces of your boat. Its compact size makes it ideal for smaller openings – perfect for ventilating lockers, heads (bathrooms), small cabins, or electrical enclosures where maintaining airflow is crucial. When installed strategically, the grille helps prevent condensation, mildew, and stagnant air by allowing cool air in and letting warm, damp air escape.
The grille is made of high-quality reinforced ABS plastic, which is impact-resistant and built to withstand marine conditions. The added UV stabilization ensures the plastic won’t degrade or discolor under intense sunlight – a particularly important feature for deck or exterior installations. Installation is very straightforward: cut a rectangular hole of 124 x 112 mm, then insert the grille flush into place and secure it with four screws (mounting holes are pre-molded). Its low-profile design means the grille won’t protrude or snag – it sits almost flush with the surface. The angled slats (louvers) are engineered to allow optimal airflow while blocking direct ingress of water from rain or splashes.
Use Cases and Recommendations:
- Ideal for ventilating small engine compartments or machinery spaces on boats where space is tight – the grille will help cool the area and vent hot air away from engines or generators.
- Suitable for battery boxes, onboard bathrooms (heads), or shower compartments – it prevents moisture buildup and odors by ensuring a continuous supply of fresh air.
- Can serve as an intake or exhaust vent in conjunction with powered ventilation systems – for example, as an inlet bringing fresh air into a cabin, or as an outlet for a fan extracting stale air.
- An excellent choice for RIBs, small yachts, and fishing boats, where the light weight and corrosion-proof nature of plastic components are advantages over metal. The grille won’t corrode and can be installed in both interior and exterior locations.
- For larger spaces or when more airflow is needed, multiple grilles can be installed – e.g., one on each side of a cabin or compartment – to create cross-ventilation and effectively refresh the air inside.
