Keep your RV rooftop air conditioner protected during storage and off-season months. The ADCO 3021 cover is purpose-built to fit Duo-Therm and Briskair 13.5K and 15K BTU units, shielding the shroud from UV degradation, wind-blown debris, bird droppings, and moisture infiltration -- so it is ready to run when warm weather returns.
Exposed rooftop AC shrouds crack and fade from UV exposure, collect leaves and nesting material, and allow cold drafts into the RV interior during winter storage. The ADCO 3021 addresses all three problems with a single, purpose-fitted cover that installs in minutes and stays put even in windy conditions.
ADCO has been manufacturing RV protective covers since 1979. The 3021 is part of their dedicated AC cover line, sized and shaped specifically for the Duo-Therm and Briskair shroud profile rather than relying on a generic one-size-fits-most design.
Heavy-duty vinyl outer with a soft jersey fabric backing resists tearing and weathering while protecting the AC shroud surface from abrasion.
Elastic parachute-style drawcord cinches snugly under the AC unit base to hold the cover firmly in place during highway travel and wind events.
Non-tearable, weatherproof seam construction prevents water intrusion at stress points -- the most common failure point on generic covers.
Blocks UV rays that bleach and crack AC shrouds, and seals out cold drafts that enter through the AC unit during winter storage.
This cover is designed specifically for the following Dometic (formerly Duo-Therm) and Briskair rooftop air conditioner models:
Installation is straightforward and requires no tools. Pull the cover over the AC shroud from one end, center it, and cinch the parachute drawcord underneath the unit base. The cover can be installed by one person from the roof in most cases.
ADCO backs the 3021 cover with a limited 3-year manufacturer warranty against defects in materials and workmanship. Retain your purchase receipt as proof of purchase for any warranty claim.
