These are heavy duty! Built to last.....the rails that come separate have feet to allow free standing on a hard surface. If you are attaching to an existing sturdy fence as we did you can forgo the railsracks as the panels can be bolted together without the racks.

We used the racks because I wanted to run the screens up above the fence to 6 feet and the top screen would have been a little shaky sticking up that far without the rack vertical rails.

The wife is ecstatic! Very elegant, durable and built to last!
