Jack Boss 14-Inch RV Roof Vent Cover Replacement Lid, White 1-Pack — UV-Resistant Reinforced Polypropylene

Jack Boss 14-inch RV Roof Vent Cover is a durable, UV-resistant replacement lid that restores ventilation and protects your trailer, camper, or motorhome from weather and debris.

If your RV’s roof vent lid is cracked, yellowed, or no longer seals, this one-pack 14 x 14 x 3.25 inch replacement from Jack Boss offers a direct-fit option built for long-term outdoor exposure. Made from reinforced polypropylene and supplied with fasteners and simple tools, it’s designed to match common 14-inch vents and many older Ventline and Elixir units.

Will this cover fit my existing 14-inch vent opening?

Yes — this vent lid is sized for standard 14 x 14 inch roof vent openings and was built to be broadly compatible. It lists fit for universal RV, camper, trailer, and motorhome roof vents, and specifically notes compatibility with many Ventline vents manufactured before 2008 and Elixir vents from 1994 onward.

• Outer footprint: 14 x 14 x 3.25 inches to match common openings
• Universal design works with most 14" vent housings
• Compatible with Ventline pre-2008 and Elixir from 1994
• Includes hardware to attach to existing vent frame

How durable is the Jack Boss vent cover against sun and weather?

The lid is molded from UV-resistant polypropylene and reinforced with a central support beam and a continuous hinge for long-term stability. Those reinforcements reduce flex and cracking from temperature cycles and sun exposure, extending usable life compared to thinner plastic lids.

• UV-resistant polypropylene to resist yellowing and degradation
• Reinforced center support beam for added rigidity
• Long continuous hinge for reliable opening and closing action
• Tested for outdoor use to meet basic durability expectations

What comes in the package and how easy is installation?

This one-pack set arrives ready for installation with 13 screws, 13 nuts, a mini wrench and a mini screwdriver so you have the basic hardware on hand. Installation is straightforward: remove the old lid, align the new cover over the vent frame, fasten the provided hardware, and test the hinge movement and seal.

• Included: one vent lid, 13 screws, 13 nuts, mini wrench, and mini screwdriver
• Simple swap-out procedure — no specialty tools required
• Hinge adjusts smoothly for opening and closing
• Hand-tighten hardware, test for secure fit and airflow

How does this vent cover affect airflow and cabin comfort?

The low-profile design maintains high-flow ventilation to help keep fresh air circulating without adding excess drag or bulk on the roof. While it doesn’t replace a powered fan, the cover preserves passive airflow and protects the opening from rain, leaves, and insects.

• Low-profile shape encourages steady cross-ventilation
• Protects vent opening from water and debris
• Works with existing vent screens and fans when present
• Durable hinge keeps lid reliably propped open or closed

Who is this product for? RV owners, trailer renovators, and DIY maintenance enthusiasts who need a reliable, easy-to-install replacement for a cracked or aged 14-inch vent lid will find this Jack Boss cover practical. It’s especially useful for those restoring older Ventline or Elixir vents, or anyone seeking a UV-resistant, reinforced plastic lid that comes with the fasteners and basic tools to complete the job without an extra trip to the hardware store.
