Custom Size 17ft x 17ft Black Rectangle Sun Shade Sail - UPF50

Our review of this custom size 17' x 17' black rectangle sun shade sail finds it best for homeowners and small businesses who need heavy-duty UV protection and a tailored fit. The single biggest reason to buy is its combination of a customized D-ring-to-D-ring fit and rugged 200 GSM HDPE construction that blocks up to 95% of UV rays while remaining water and air permeable. Installation takes some planning but delivers a cooler, more comfortable outdoor area and a durable canopy built to handle tough conditions.

Key Features

• 95% UV blockage: The 200 GSM HDPE fabric blocks up to 95% of harmful UV rays, giving reliable sun protection for patios and play areas.
• Temperature reduction: The shade sail can lower ambient temperatures by as much as 15 degrees compared to unshaded spots, making outdoor time more comfortable.
• Customizable fit: Measurements are taken D-ring to D-ring so the canopy can be tailored to odd shapes and specific mounting points for a neat installation.
• Durable construction: Stainless steel D-rings, reinforced edges and double-layer stitching improve longevity and resistance to fraying.
• Permeable design: The fabric is water and air permeable, which helps avoid wind stress and prevents pooling after rain.
• Three-year assurance: The product includes a three-year assurance that covers expected durability issues for peace of mind.

Who It's For

This shade sail suits homeowners, cafes, and yard owners who want a tailored canopy solution that prioritizes UV defense and durability. It is especially practical for those mounting to fixed points like trees, posts, walls or roofs where a specific D-ring-to-D-ring measurement produces a clean fit.

It may not be ideal for buyers who expect a rigid waterproof awning or those who need an off-the-shelf, instant-fit shade without taking precise measurements; the custom approach requires care when measuring and planning mounting gaps for best tension and appearance.

Frequently Asked Questions

How should I measure for a custom fit?
Measure from D-ring to D-ring along the planned attachment points and allow the recommended gap between D-rings and poles for proper tension.

Is the sail waterproof?
The fabric is water permeable rather than fully waterproof, which helps prevent pooling but will not act as a solid rainproof roof.

How durable is the material in wind?
The 200 GSM HDPE and reinforced stitching offer good wind resistance; customers report strong performance even in high gusts when properly installed.
