4 ft x 17 ft Grey Straight-Edge Sun Shade Sail Rectangular - UV

Our review of the 4 ft x 17 ft grey shade sail finds it best suited for homeowners and renters who want a durable, no-fuss canopy to cut sun and lower temperatures over a narrow patio, pergola or walkway. The single biggest reason to buy is the heavy-duty construction: woven 180gsm non-recycled HDPE fabric with reinforced webbing and stitched 304 stainless steel D-rings means this sail feels built to last and is ready to hoist once you have secure anchor points. Installation is straightforward and the fabric breathes, so it blocks sun while allowing airflow beneath.

Key Features

• Material: 180gsm non-recycled HDPE with industrial cross-weaving provides long-lasting strength and resists stretch under tension.
• Corner Hardware: 304 stainless steel D-rings are stitched into each corner to give reliable attachment points for the included nylon ropes.
• UV Protection: The fabric blocks over 95% of harmful UV rays while still permitting a light breeze and reducing temperatures underneath.
• Design: Straight flat edges increase usable shaded area and the manufacturing technique helps prevent drooping over time.
• Ready to Install: Thick, durably-enforced webbing and included ropes make setup quick when leaving 1-2 ft to attach to posts or walls.
• Versatility: Sized and finished for patios, pergolas, pools, gardens and vehicle cover applications where a rectangular canopy fits best.

Who It's For

This 4 ft x 17 ft grey sail suits people who need a narrow, long canopy for walkways, side patios, pergola slats or to create a shaded corridor between structures. It is especially useful where UV protection and airflow are both priorities and where mounting points allow the recommended 1-2 ft of clearance at corners.

Those who need a very large shade area or a decorative, heavy-insulation fabric for winter use should look elsewhere; this product is optimized for summer sun protection and seasonal outdoor use rather than full waterproofing or permanent roofing.
