The Keystone Fabrics Diamond Plus 6-ft. Outdoor Sun Shade offers up to 88% UVA blockage and is easy to set up. This exterior solar shade blocks the sun before it hits your window or patio, dramatically reducing heat build-up, fading of furniture and glares on your T.V. or computer. It's constructed of weather-resistant PVC-coated polyester in a choice of colors, and it's easy to operate with a simple pull of a cord. Place the cord on the left or right hand side. Brackets are included for easy mounting on the wall or the ceiling and a 3-sided, oil-rubbed, bronze valance fully encloses and protects the shade when it's rolled up. Enjoy excellent coverage from this shade that measures 6 feet across and 8 feet long.About Keystone Fabrics Family-owned and operated since 1995, Keystone Fabrics is located in Erie, CO, and focuses on offering the best quality sun protection products at competitive prices.
