SO pleased we went with tgis product .. due to the grade of our backyard, we stepped the panels amd it still turned out beautiful .. installed an entire backyard in one weekend .. super sturdy and easy to install product .. used Quikrete Fast Setting for the posts .. top caps install separately but they provide plenty of fast drying pvc glue .. A product and Wayfair delievered well before originally estimated due date .. thank you Wayfair and Wam Bam Fence company
