Installed horizontally on a 36" tall deck railing facing golf course and added a bit of privacy, used only zip ties after screwing the panels together with the included nuts and bolts and it's a very windy deck...no problems, whatsoever, but then again, it's attached to the existing railing using just a handful of zip ties on 23ft of railing, I did not use the included stands. It says it's double sided, but there is a slightly different look from front and back as the back is more inset, FYI.
