If your RV’s roof vent cover is cracked, faded, or just not doing its job anymore, this Kojem replacement set is exactly what you need. These 14-1/4 inch x 14-1/4 inch black covers are made from automotive-grade plastic, so they’re tough, waterproof, impact-resistant, and built to last. They fit universal RV, camper, and trailer roof vents, and are specifically compatible with Ventline models made before 2008 and Elixir vents from 1994 onward. Just double-check your vent model before ordering to make sure it’s a match. These covers help keep the air in your RV fresh when open, and when closed, they seal out rain, heat, and debris. Installation usually involves sliding them into place on the existing rail – though if you’re not comfortable doing it yourself, professional installation is always a good idea. You get three covers in the pack (no hardware included, but instructions are provided), so you can replace multiple vents or keep spares on hand. A simple upgrade that makes a big difference in comfort and protection.
