The Dometic Full Cover Slide Topper comes in a case similar to the 9500 Case Awning. The awning protects your RV slide out from unwanted debris. There are no buttons needed to extend the Slide Topper over your RV slide out. The awning automatically extends and retracts with the RV slide out for easy setup and tear down. The metal case protects the Slide Topper when not in use.
