Very impressed with this shade sail by Royal Shades. Its  a grey 16' x 20' rectangle. The craftmanship is superb. The edges are well made with heavy duty reinforced stitched seams, that are extra-stitched in the corners for added strength. The D rings come attached in the corners. I love the options that Royal Shades offer such as the triangle, square and rectangle shade sail as well as fencing and private shade screens. Would definitely recommend. We be putting mine up as soon as I have the posts concreted in the ground. Posts are not included.
