View 00-335001 productMAXXAIR UNIMAXX RV Vent Lids: Hinge Parts & Installation
A cracked RV roof-vent lid can often be replaced without replacing the complete vent. MAXXAIR's UNIMAXX kits provide a universal-style replacement dome and hinge arrangement designed for many Elixir, Heng's, Jensen and Ventline vent housings. Choose the colour, then inspect your existing crank operator, roof flange and vent-cover clearance before installing.

UNIMAXX universal vent lid — smoke
Manufacturer part number: 00-335002
View 00-335002 productWhite and smoke versions
| MAXXAIR part number | Lid colour | What the kit replaces |
|---|---|---|
| 00-335001 | White | Damaged exterior vent lid and associated hinge connection on a suitable crank-operated roof-vent assembly |
| 00-335002 | Smoke | Same universal replacement design with a smoke-coloured exterior lid |
Both are replacement-lid kits, not complete roof vents, powered fan assemblies or exterior rain covers. A universal design reduces dependence on the old hinge style, but the existing roof housing and hand-crank linkage still must be suitable for the installation shown in the instructions.
Factory kit contents
| Component | Number supplied | What it does |
|---|---|---|
| Universal replacement lid | 1 | The new roof-vent dome |
| Universal hinge | 1 | Attaches the new lid to the existing vent frame |
| Lift-arm slide / clip | 1 | Connects the original lift arm to the new lid's T-bar track |
| Screws | 4 | Fasten the hinge at the roof-vent flange |
| Flat washers / lock washers / nuts | 4 of each | Secure the hinge fasteners from the inside |
Existing vent housing
The roof-mounted flange and its seal remain in place if sound.
Universal hinge
Positioned against the housing and fastened using the new screws and washers.
Replacement dome
Connected to the universal hinge and seated against the original perimeter gasket.
Lift-arm clip
Links the old crank-operated lift arm to the lid track so it opens and closes correctly.
Before starting
- Open the existing vent and remove the interior garnish, crank handle and screen frame as shown by MAXXAIR.
- Inspect the existing lift operator and roof-flange condition. The kit is not a replacement for a damaged operator or rotten roof structure.
- Check that the universal hinge has a sound mounting area and will clear any existing vent rain cover. The instructions specify a 3/16-inch drill bit for the hinge mounting holes.
- Use the manufacturer's fastener arrangement and seal previously unused roof holes properly. Reconnect the lift arm, then test opening and closing before finishing.
Manufacturer installation drawings
The factory instructions illustrate the lid, hinge, screws, roof-flange positioning and lift-arm clip. The diagram below shows the hinge connection and mounting sequence.

For the lift-arm slide/clip connection, open drawing page 4. This model-specific drawing is also useful when an older Ventline Ventadome slide differs from the universal clip.
