Automatic Awning Support works automatically with your manual patio awning, simply roll up your awning and the patented action receives the roller and gently supports it, eliminating all the weight and natural sag that you normally get in the middle of the roller. When you unroll your awning, the cradle automatically releases the roller and pivots away from the canopy, ready to accept the roller again when you put the awning away. Will not harm the fabric or metal wrap of the awning - for use on straight side applications only, it will not work on curved coaches. Fits most awning brands. 2 Year Limited Warranty on parts. Polar White finish/casting in color.
