Custom-Made Shade Sail-Right Triangle

Used this along the diagonal slope of our deck stairs. It adds a sleek architectural touch while keeping the stair railing cool to the touch on hot summer days.

Had a generic triangle sail from Amazon that sagged terribly along the long edge. This custom one has curved edges cut into it so when you pull the corners tight, the entire sail stays taut.

The stainless D-rings are solid and the cross-stitching at the 90-degree corner is very substantial. You can crank down on the turnbuckles without worrying about tearing seams.

Custom size was accurate and arrived in good condition. Easy to hang.

Triangular sails are so much easier to tension than 4-corner ones. Even on breezy afternoons, the breathable mesh lets air pass through without putting too much strain on our wall mounts.

Needed shade just over the spa nestled in the corner of our fence. Keeps the harsh sun off our faces in the afternoon without shading out the rest of the open patio.

Standard equilateral triangles left huge awkward gaps against our 90-degree exterior wall. Having a true right-angle custom sail made all the difference. Fits flush into the corner and provides full coverage.

I was nervous ordering a right-angled sail because if the hypotenuse is off, the whole thing sags. I followed their guide and subtracted allowance for the turnbuckles. It arrived, hooked right in, and tensioned drum-tight with no diagonal wrinkles.

Sized correctly to our specs and keeps the deck cool in the afternoon. Solid 4-star product.

Measurements were accurate to the inch. Fabric is durable, lets hot air escape, and blocks the intense sun effectively.

The custom cut is accurate and the material is sturdy. The sand color looks a bit lighter in direct bright sunlight than on my screen, but it still blends nicely with our stucco house.

Mounted this right outside our breakfast nook window where the morning sun was blinding. It cut the glare completely and lowered the room temp by several degrees.

High quality fabric, blocks the harsh UV rays, and the turnaround time was great for a custom size.

Sturdy fabric, does the job nicely.

The 90-degree right angle matched our patio corner perfectly. The graphite color is a shade darker than I expected from the photos, but it blocks the harsh sun very effectively.

Fit the corner of our patio perfectly. Good shade.

Material is tough and the 3-point mounting was easy. Just remember the sides curve inwards slightly to maintain tension, so the actual shaded area along the edges is slightly less than a flat straight-edge triangle.

Custom order arrived surprisingly quick. Hooked up two corners to the fascia board and one to a 4x4 post. Quick, painless DIY project that looks custom-made by a contractor.

Try finding a right triangle shade sail at local big box stores—virtually impossible. Sunlax made this to our exact specs. Stitched reinforced corners and D-rings are top tier.

If you have an outdoor corner between two exterior walls, this is the only shape that makes sense. Zero wasted space and crisp, clean lines along the wall.
