Retractable awnings are primarily for sun protection and should not be left out in windy conditions or when the area the product is covering is not being used. Wind is an unpredictable force, however, and can quickly change direction and intensity. In “real life” applications the rule of thumb is: if you are comfortable sitting outside dining or reading the paper, then it is probably safe to use your awning. The concern with wind is a lifting effect on the awning rather than the downward force; therefore, the greater the pitch, the more wind resistant the unit is.
