I have an alumawood patio that has the slats on the ends, but this is where we spend most of the time with the BBQ's! This fits perfectly underneath at an angle to get both grills and provides shade from our very hot desert sun!, I am also completely Impressed and 100% definitely recommend buying from this website, I have bought an outdoor grill from this website before and today pressed the trigger for the umbrella. Each time they provided me with the best quality items as well as their outstanding customer service throught the shopping and shipping process. Dont risk it and buy it somewhere else, its not worth it! Thank you modern productions!
