Right Triangle Sun Shade Sail 17ft x 18ft x 24.8ft Beige - Cooler

Our review of this right triangle sun shade sail finds it best suited for homeowners and small commercial outdoor spaces that need reliable sun protection without a permanent structure. The single biggest reason to buy is its combination of 95% UV blockage and durable 200 GSM HDPE construction, which gives effective shade and temperature reduction up to about 15 degrees compared with unshaded areas. It installs flexibly to trees, walls, or poles and includes reinforced corners with stainless steel D-rings for heavier duty use.

Key Features

• 95% UV blockage: Blocks most harmful rays for safer outdoor time and protects items and people beneath the sail.
• 200 GSM HDPE fabric: Provides long-lasting strength and resists fraying thanks to double-layer stitching and reinforced edges.
• Temperature reduction: Lowers ambient temperature by up to about 15 degrees in shaded areas, improving comfort for patios or play areas.
• Flexible installation: Can be mounted to trees, roofs, walls or poles and adjusted by setting gaps from D-ring to pole for proper tension.
• Commercial standard hardware: Stainless steel D-rings and reinforced corners suit heavier use in residential and light commercial settings.
• Customizable sizing: Made to order from D-ring to D-ring so the fit matches the measured installation area.

Who It's For

This shade sail is ideal for homeowners, small business patios, pet runs and garden areas that need a removable sun-blocking canopy with a custom fit and strong materials. The 17' x 18' x 24.8' right triangle shape works well where triangular coverage fits better than rectangles, such as corner setups or angled patios.

Those who want a precise, straight-edged sunroof or a very large permanent structure should look elsewhere; this product is a made-to-order fabric sail designed for tensioned mounting and works best when anchored to existing posts, walls or trees.

Frequently Asked Questions

Is this sail waterproof?
Answer. No, the fabric is water and air permeable, so it reduces sun and heat but does not provide full rain protection.

How should I measure for a custom fit?
Answer. Measure from D-ring to D-ring at the planned anchor points and allow recommended gap clearances of about 0.5 ft at corners or reduce each side by 1 to 1.5 ft as instructed for tensioned mounting.

Can it withstand wind and sun long term?
Answer. Yes, the 200 GSM HDPE with double stitching and stainless steel D-rings is built for durability and commercial-standard use, but proper tensioning and secure anchors are important for longevity.
