White UniMaxx universal replacement vent lid for many standard RV roof vent assemblies, including Elixir, Heng’s, Jensen, Ventline, and similar non-powered roof vents.
The Maxxair 00-335001 UniMaxx is designed to simplify RV roof vent lid replacement. Instead of matching the exact original lid manufacturer, production year, or hinge style, the UniMaxx uses a universal hinge design that works with many standard RV roof vent assemblies.
This white replacement lid is commonly used to replace damaged or old lids on Elixir, Heng’s, Jensen, Ventline, and other standard roof vent assemblies. It is preassembled and includes mounting hardware for a cleaner, more complete repair.

This UniMaxx replacement lid is designed for many standard non-powered RV roof vent assemblies. It is not intended to replace lids on powered fan lid assemblies. Before ordering, confirm that your existing vent is a standard roof vent lid application and not a powered roof vent fan lid.
Before Starting: Work safely on the RV roof and avoid installation in wet or windy conditions. Inspect the existing vent frame, hinge area, and lid seal before replacing the lid. Basic Installation Steps: 1. Confirm Application: Verify the vent is a standard roof vent lid application and not a powered fan lid assembly. 2. Remove Old Lid: Detach the damaged or old lid from the existing vent frame and hinge area. 3. Inspect Vent Frame: Check the frame, seal, hinge area, and operator for cracks, corrosion, or damage. 4. Position UniMaxx Lid: Align the preassembled UniMaxx lid and universal hinge with the existing vent assembly. 5. Install Hardware: Attach the lid using the included mounting hardware and the recommended installation method for the vent style. 6. Test Operation: Open and close the vent to confirm the lid moves smoothly and seats evenly. 7. Check Seal: Confirm the lid closes properly against the vent frame to help prevent leaks.

To confirm compatibility before ordering, have the following ready: • Roof vent brand/model, if known • Photos of the existing lid and hinge area • Whether the vent is powered or non-powered • Existing lid dimensions • Photos of the interior operator/crank area, if available Why this matters: The UniMaxx lid is designed to eliminate many hinge-matching issues on standard vents, but powered fan lids and specialty vent assemblies may require model-specific replacement lids.
The UniMaxx lid is designed for many standard RV roof vents, but it should not be used to replace powered fan lid assemblies.
If replacing the lid does not resolve leaks or operation issues, inspect the lid seal, vent frame, hinge area, crank/operator mechanism, and roof sealant.
