Cracked, faded, or broken vent lid? This is the genuine MaxxAir replacement lid that brings your MaxxFan or MaxxFan Plus roof vent back to full function and a clean look. A direct drop-in fit -- no cutting, trimming, or adapter hardware required.
The 10A40002K lid is the factory-specified replacement cover for the full MaxxFan lineup, including the standard MaxxFan and MaxxFan Plus series. If your existing lid has stress cracks from UV exposure, hail damage, or road debris, swapping it out is one of the fastest DIY repairs on an RV roof -- typically under 15 minutes with no special tools.
The lid is molded in high-density polypropylene, the same material used on the original unit. It resists UV degradation, holds up to temperature swings from below freezing to desert heat, and will not warp or yellow as quickly as lower-grade plastics. The white finish matches the factory appearance and blends with most RV roof profiles.
Engineered to the same dimensions and hinge points as the factory lid. Snaps into the existing MaxxFan frame -- no modifications needed.
Impact-resistant and UV-stable material holds shape through temperature extremes common in RV rooftop environments.
Fits the standard MaxxFan and MaxxFan Plus model roof vents. One part number covers the full model family.
Package contains one (1) replacement vent lid in white. No additional hardware is included or typically required for installation.
This lid is designed to fit the following MaxxAir roof vent families:
If you are unsure whether your vent is a MaxxFan or MaxxFan Plus, check the label on the interior vent frame or the original installation paperwork. Both series share the same 14 x 14 inch standard RV roof opening and use this same lid profile.
High-density polypropylene (HDPP) is the standard for RV roof vent lids because it balances rigidity with enough flex to absorb minor impacts without shattering. It is also chemically resistant to most roof cleaning agents and protectants.
The white finish reflects radiant heat, helping reduce interior temperatures versus darker-colored lids -- a practical advantage for full-timers and summer campers who rely on their MaxxFan for ventilation.
