Livpow RV Roof Vent – 14″ x 14″
The Livpow 14″ x 14″ vent replaces Ventline, Jensen, and Elixir models, offering compatibility with roof thicknesses from 1-1/4″ to 2-1/4″ and standard 14″ x 14″ openings. A one-piece seamless frame provides leak resistance and weather tightness, while a translucent white lid allows natural light inside without sacrificing weather protection. This option suits trailers and RVs that use standard vent footprints and seek a straightforward, affordable upgrade.
Camp’N 14.5″ Universal Roof Vent Cover
The Camp’N universal cover is designed to fit most popular roof vents, including Ventline units prior to 2008 and Elixir models starting in 1994. Measuring 14″ x 14″ (andiented for 14.5″ x 14.5″ openings in some variants), it uses impact-resistant plastic for durability and long life. This option emphasizes broad compatibility, straightforward installation, and reliable weather resistance for families upgrading an aging vent lid.
Jack Boss Roof Vent Cover – 14 Inch
This 14″ vent cover from Jack Boss is built with UV-resistant polypropylene and includes a reinforced center support beam and a long continuous hinge for easy adjustment. The kit comes with screws, nuts, a mini wrench, and a screwdriver, making installation convenient for DIY enthusiasts. It supports universal RV applications, including older Ventline and Elixir vents, and aims to endure exposure to sun, rain, and temperature changes while maintaining a secure fit.
Camp’N 14″ Universal RV Roof Vent Cover (2-Pack)
The 2-pack Camp’N vent covers provide a versatile option for trailers or motorhomes with multiple vents. The covers maintain a universal 14″ fit and are designed to replace various vent lids, including those from Ventline and Elixir. Enhanced durability and weatherproofing help protect against rain and snow, while the two-pack format supports cost-effective upgrades for fleets or multi-vent trailers.
MAXXAIR Maxx II Vent Cover
The MAXXAIR Maxx II vent cover emphasizes a one-piece, wind-resistant design using high-density polyethylene with UV protection. Its aerodynamic profile reduces wind resistance while keeping rain, leaves, and pests out and allowing for continuous airflow. This option is well-suited for trailers exposed to strong crosswinds or those seeking a sturdy, low-maintenance cover that blends with most RV exteriors.
Buying Guide
Key considerations when selecting a roof vent cover or lid include compatibility with your current vent type and opening size, material durability, and weather performance. If you have an aging vent, compatibility with Ventline, Elixir, or Jensen models can simplify replacement. Look for UV-resistant plastics to resist sun damage, and consider models with hinges or reinforced frames for extra longevity. For trailers used in extreme climates, wind resistance and rain protection become a priority, while transmission of light through a translucent lid can help keep interiors bright without opening the vent.
Durability versus price is another balance to assess. Lightweight lids may be easier to install but offer less protection in heavy rain or snow. Heavier, reinforced constructions protect against impact and gusts but may require more effort during replacement. When purchasing, check if the product includes hardware or requires purchase separately—some listings include screws, nuts, and basic tools, while others are sold as a lid only. If you maintain multiple vents, consider a two-pack option to save on replacement costs and ensure consistent performance across all openings.
Installation considerations also matter. Some lids are designed for universal fit and straightforward snap-in installs, while others rely on drilled screws and sealing gaskets. Ensure you have the correct gasket or trim ring to seal the opening and prevent leaks. Finally, evaluate aesthetics: a white, UV-stable lid blends with most trailer exteriors, while translucent options can bring in light without sacrificing protection.
