Measurements are taken corner to corner and the sail is delivered with curved edges to prevent sagging, so the biggest reason to buy is the precise custom fit that keeps the fabric taught and visually neat while blocking most solar heat.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom fit measurements:\u003c\/strong\u003e Corners are measured corner to corner and the sail is cut so the curved edges produce a tight, clean appearance without excess sagging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable fabric:\u003c\/strong\u003e Made from virgin polyethylene for lightweight strength and long life in outdoor conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStrong UV protection:\u003c\/strong\u003e The fabric blocks up to 95% of UV rays and reduces visibility by up to 90% for cooler, shaded spaces and added privacy.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-season use:\u003c\/strong\u003e Designed to provide sun protection in summer, reduce overnight frost, and shed light rain for multi-season utility.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3-year limited warranty:\u003c\/strong\u003e Backed by a multi-year warranty that provides reassurance about material and workmanship.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLocally made to order:\u003c\/strong\u003e Custom sizes are crafted locally and delivered on schedule, which helps ensure accuracy for odd or exact spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe shade sail is ideal for homeowners with patios, pools, driveways, carports, gardens, or balconies who need sizable coverage and want the confidence of a tailor-made fit.
