VanEssential Magnetic Insulated Roof Vent Cover for 16.5" x 16.5" Vents — Black, Magnet-Backed Blackout

Keep your campervan, conversion, or overland vehicle comfortable, private, and light-free with an easy-to-install vent cover built to fit the 16.5" x 16.5" flange found on popular MaxxAir and Fantastic Fan units. The VanEssential design combines automotive-grade insulating layers, external black fabric for complete darkness and privacy, and sewn-in rare earth magnets so the cover stays firmly in place whether you're parked overnight or rolling down the road. It folds flat and stows in the included bag when not in use.

How does this cover help control interior temperature?

The insulated core reduces heat transfer across the roof vent opening, slowing heat gain in summer and heat loss in winter. That means your vehicle’s interior climate is easier to manage with less reliance on fans, heaters, or running the vehicle.

• Automotive-grade insulation layer reduces conductive heat flow
• UV-resistant outer materials withstand sun exposure
• Black exterior minimizes light penetration while still aiding thermal performance

Will it really block light and provide privacy?

Yes—every cover uses an external-facing black fabric and is sized to the 16.5" x 16.5" flange to eliminate gaps where light could leak through. The snug fit combined with the blackout fabric gives reliable privacy for sleeping, changing, or protecting interior gear.

• Full blackout exterior blocks daytime and streetlight at night
• Precision fit prevents edge light leaks common with generic covers
• Secure magnetic attachment keeps edges flush against the vent frame

How does the magnetic attachment work and is it secure while driving?

Rare earth magnets are sewn into the cover at strategic positions so the magnet-to-metal contact holds the panel firmly against the vent flange. The magnets are sized and located to resist movement from vibrations or wind while driving, yet let you remove or reposition the cover quickly when needed.

• Strategically stitched rare earth magnets for reliable hold
• Designed to remain in place whether parked or on the go
• Easy pull-away removal when you need to open the fan or vent

How easy is installation, storage, and daily use?

Installation takes only minutes—align the cover over the closed vent and let the magnets seat on the flange. The cover folds compactly and fits in the included storage bag for neat stowage when the vent is in use, making it a practical everyday accessory for vanlifers and weekend campers.

• Quick set up and takedown in minutes
• Folds flat for compact storage in the included bag
• Lightweight, durable construction built for frequent use
