Add-A-Damper Conversion Kit

Turn your damperless vent upgrade into a dampered vent upgrade.

If you have already purchased our Air Vent Upgrade Kit - Without Damper (For Airstream Trailers), but would like to add the damper functionality to transform your kit into our dampered kit, the Add-A-Damper upgrade is for you. This kit contains all the parts required to modify a no-damper kit to add the damper.
