Carefree SideOut Kover III, Black Vinyl fabric with Black deflector; for roof size range 142 inch-149.9 inch; flange size range 147 inch-154.9 inch; fabric width 153 inch. The SideOut Kover III includes a wind deflector and integrates with the patio and window awnings for a sleek, modern unified look. Protect your investment by covering your slide rooms with the SideOut Kover III. This slide out awning works automatically with your slide room and helps protect it from damaging leaves, debris and water. The concealed, built in cradle support prevents the roller assembly from sagging to enhance the unified, sleek, modern look of your RV. All mounting screws are completely covered and concealed to finish off the clean look. The roller tube, bracket assemblies and wind deflector are all made of extruded aluminum for long lasting durability. Deflector prevents any billowing of fabric while traveling. Tip: under certain conditions, water may pool on top of any brand of extended slide out cover. If you retract your slide out in steps (stop and go), the roller can take up the fabric and dump most of the water.
