1.Perfect design: the awning is made of Oxford tarpaulin with sturdy seams on each side, stainless steel Drings on each edge and wrapped with matching rope to ensure solid installation. (It is recommended not to use it in heavy rain and snowstorms). 2.Installation – The waterproof awning must be installed at a high voltage angle of 2040 degrees so that water drains and points upwards, otherwise water accumulates. 3.UV protection: the patio sun shade provides 90% shade and over 95% protection from harmful UV rays. Ideal for gardens, patios, lawns, ponds, decks, backyards, fenced yards, parks, pools, BBQ areas and other outdoor activities. 4.Size: Please measure the installation area carefully before purchasing. Between the Dring and the attachment point, leave approx. 0.5 24.25 inches distance. All edges are slightly curved so they can be tightened.
