We lost our shade structure during an unusually stormy and windy soccer game one fall. My brother had purchased the same structure and broke his frame in a similar manner. Instead of throwing them out, we took apart the broken leg and replaced it from one of the good ones from my brother's frame. We were even able to use the canvas cover and walls on another shade frame that a friend was discarding.
It's great to get another season of use out of these structures rather than just tossing it into the landfill.
