Custom Size 9ft x 10ft x 13.5ft Gray Right Triangle Sun Shade Sail

In this review of the custom size right triangle sun shade sail, the bottom line is simple: buyers who need a tailored, heavy-duty shade for patios, play areas, or commercial outdoor seating will appreciate the strong sun protection and flexible installation. The reviewer found the sail's main selling point to be its 95% UV blockage from durable 200 GSM HDPE fabric, which reliably reduces surface temperatures and creates comfortably cooler shaded zones compared with unshaded areas.

Key Features

• 95% Sun Protection: The 200 GSM HDPE construction blocks up to 95% of harmful UV rays for safer outdoor time.
• Temperature Reduction: The sail lowers ambient surface temperatures by up to 15 degrees compared to unshaded spots, helping outdoor spaces stay cooler.
• Custom Fit: Measured D-ring to D-ring for a tailored canopy, with options to request straight edges or other adjustments.
• Durable Construction: Reinforced edges, double-layer stitching and stainless steel D-rings improve resistance to wear and wind stress.
• Permeable Design: The material is water and air permeable, so it sheds some moisture while allowing airflow to reduce wind load.
• Easy Installation: Can be attached to trees, roofs, walls or poles with standard mounting hardware, with recommended clearance guidelines at each corner.

Who It's For

This shade sail suits homeowners and small-business operators who need a tailored shade solution for decks, patios, playgrounds or outdoor dining areas and who value strong UV protection and cooler shaded zones. People who plan the install can benefit from the customizable D-ring measurements and the ability to ask for straight edges if a precise look is required.

Those who want a temporary umbrella-style solution or expect a completely maintenance-free lifetime should look elsewhere; a couple of users reported mixed long-term durability in very harsh sun exposure, so high-UV climates may require periodic inspection or replacement after extended seasons.

Pros & Cons

Pros

Frequently Asked Questions

Can this sail be trimmed or resized locally?
Answer. It is supplied to D-ring measurements for a custom fit; for straight edges or other adjustments, contact the maker for customization rather than trimming the finished sail.

Is the material waterproof?
Answer. The 200 GSM HDPE fabric is water and air permeable, so it sheds some rain but is not a fully waterproof tarp.

What clearance is needed at corners?
Answer. Allow at least 0.5 ft clearance between D-rings and poles, or reduce by 1 to 1.5 ft per side as recommended for optimal tension and performance.
