When inflated, Awning Buddies provide support for slide-out awnings as taunt or loose, as you prefer. Simply air them up underneath your awning, or on the ground, and slide them up underneath your slide-out awning. They are made from a high-grade rubber coated material that tolerates 130°F to -30°F temperatures. Check out our introductory and instructional videos on Facebook we have created to better assist you! There are 19 different sizes to choose from after you have properly measured the lengths of your awnings.
