Don't buy one. My awining is 10 years old and Sunsetter quit making key parts to the operation of these awnings. Like the main spring that allows you to roll the awning back up. Sunsetter refused to support their products. The operator when I called told me that Sunsetter does support their products. I asked how Do I fix an awning that cannot be rolled up and she said you can't becuse Sunsetter does not make the parts anymore.
