I needed a PVC arbor to replace the wood arbor that deteriorated beyond repair after 25 years.  It was under a tree and always in the shade, so my plan was that the PVC would be a better choice for the spot. It went together easily and although the box was open on one end when it arrived all the parts were present.  Although it is not as sturdy as a cedar arbor I purchased for another spot in my yard(also from Wayfair) it is maintenance free and since I supported it in concrete should provide years of enjoyment.  Quality materials.
