Calvana RV Vent Covers 2-Pack — Universal Side Vent for Trailers & Trucks, Black, 8x6 Bolt-On, UV-Resistant

Calvana 2 Pack RV Vent Covers are universal side vents that bolt onto pre-cut 3" openings to improve airflow and protect cargo areas in trailers, trucks, and RVs.

These black, bolt-on vent covers from Calvana are built to be a durable, straightforward ventilation upgrade for enclosed vehicles. Each pack contains two vents sized for an 8" x 6" exterior footprint with an inner opening dimension suited for a 3" pre-cut hole. They are made of heavy-duty plastic designed to resist UV, weather, and vibration, and include 18 self-tapping screws for a simple installation.

How do these vent covers improve airflow inside a trailer or RV?

Fitting side-mounted vents increases passive air exchange, helping reduce trapped heat and stagnant odors without electrical power. The Calvana vents create a dedicated path for air movement while limiting direct entry of rain and debris.

• Inner opening sized to match standard 3" pre-cut holes for consistent airflow.
• Side-mount position encourages cross-ventilation when combined with other vents.
• Slotted grill design deflects rain while allowing air to pass freely.

Will these vents fit my vehicle or trailer?

These vent covers are designed for universal compatibility across travel trailers, cargo trailers, truck caps, utility trailers, and camper vans, provided you have a 3" diameter hole already cut in the side panel. The outer face measures 8" x 6", so ensure there’s enough flat surface area for mounting.

• External dimensions: 8" x 6" to confirm space for mounting.
• Inner diameter: 3" inner opening; outer collar diameter 4.125" for seating.
• Works with common RV and trailer panel thicknesses using the included screws.

How difficult is installation and what comes with the package?

Installation is intentionally simple: these vents bolt on using the provided self-tapping screws and basic hand tools. No special wiring or adhesive is required, and the included hardware is sized for typical trailer skin materials.

• Bolt-on design with 18 self-tapping screws included for two vents.
• Fits into a pre-cut 3" hole; ensure correct hole size before mounting.
• Installation can be completed in minutes per vent by one person.

How durable are Calvana vent covers for long-term outdoor use?

Calvana vents are molded from heavy-duty plastic formulated to resist the common stresses of road use: UV exposure, vibration, and weather. Their construction minimizes the need for frequent replacement and keeps the vent functional in varied climates.

• UV-resistant material reduces fading and brittleness over time.
• Weather-resistant design prevents water intrusion and corrosion-free mounting.
• Rugged construction tolerates vibration and road shock without cracking.

Who is this for: The Calvana 2 Pack RV Vent Covers are ideal for DIYers, RV owners, trailer fleet managers, and anyone who needs a cost-effective way to increase passive ventilation without electrical components. They work well for seasonal campers, tradespeople carrying temperature-sensitive gear, and owners of older rigs that need simple, durable vent upgrades.
