Custom Size 17ft x 20ft x 26.2ft Right Triangle Sun Shade Sail - UPF50

Our review of this custom size right triangle shade sail finds it best suited for homeowners and light commercial users who need a tailored sun protection solution for a specific outdoor area. The biggest reason to buy is its balance of practical sun blocking and airflow: made from 200 GSM HDPE it delivers 95% sun protection while remaining water and air permeable, which keeps covered spaces cooler without trapping moisture. Installation is flexible enough to attach to trees, posts, or building anchors, so it works where rigid structures do not.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays to protect people and furnishings beneath the sail.
• Temperature reduction: The breathable weave can lower surface temperatures by up to 15 degrees compared with unshaded areas for a noticeably cooler space.
• Custom sizing: Measured D-ring to D-ring, the sail is made to order so it fits irregular spaces and specific triangular footprints precisely.
• Durable construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve longevity and resist fraying at stress points.
• Easy installation: The sail installs to trees, walls, roofs or poles using common mounting hardware and spacing guidance for optimal tension.
• Commercial standard: Built to a heavier gauge and offered with a three year assurance for confidence in regular outdoor use.

Who It's For

This shade sail is ideal for homeowners, small businesses or public spaces needing a custom triangular coverage where pre-made sizes do not fit. It fits patios, poolside zones, playgrounds and outdoor seating areas where airflow and UV protection are priorities.

Those who should look elsewhere include buyers wanting a fully waterproof canopy or a temporary pop-up shelter; the sail is water and air permeable rather than fully waterproof, and it is designed as a permanent or semi-permanent installed shade solution rather than a portable umbrella replacement.

Pros & Cons

Pros

• High UV protection keeps covered areas safer from sun exposure.
• Breathable fabric reduces temperatures while allowing air and water to pass, preventing pooling.
• Custom D-ring to D-ring sizing and reinforced hardware give a tailored, robust fit.
• Included three year assurance adds value and reassurance for regular outdoor use.

Cons

• Durability reports are mixed over long term intense sun exposure, so very hot, high-UV climates may reduce lifespan.
• Not fully waterproof, so it will not keep heavy rain from passing through or protect against storms.

Frequently Asked Questions

Is this shade sail waterproof?
Answer: No, the fabric is water and air permeable so it sheds light rain but will not be fully waterproof in heavy storms.

How should I measure for a custom fit?
Answer: Measure from D-ring to D-ring where the sail will be mounted and provide those exact dimensions so the sail is made to the specific triangular footprint.

What installation spacing is recommended?
Answer: Leave at least 0.5 ft gap between D-rings and mounting poles; if tightening sides reduce the gap by 1 to 1.5 ft per side for optimal tension.
