The Furrion Chill Cube air distribution box is available only in white, which appears as an off-white or cream color. For installation, you will need the Furrion Chill Cube air conditioner along with its compatible air distribution box; these two components are all that is required. The package includes mounting hardware and screws designed to accommodate roof thicknesses from 3 to 6 inches. Since your facade is approximately 4 inches thick, the supplied screws should be adequate without needing to order longer ones. Additionally, the foam separator included with the unit provides sufficient insulation and separation for proper installation. If you require alternative screw options, a variety of mounting screws are available for purchase separately.
