Custom Size 17ft x 17ft Black Square Sun Shade Sail - Tight Fit, UV

Our review of this Custom Size 17' x 17' Black Square Sun Shade Sail finds it best for homeowners and outdoor-space owners who need a tailored, heavy-duty canopy that blocks heat and adds privacy. The single biggest reason to buy is the made-to-measure fit and curved edges that keep the fabric taut and reduce sagging; measured corner to corner and crafted locally, this shade delivers a clean, low-profile look while blocking up to 95% of UV rays.

Key Features

• Made for a Perfect Fit: Corner-to-corner measurements and curved edges keep the sail tight and prevent the typical sag that shortens usable life.
• Durable & UV-Blocking Material: Virgin polyethylene construction provides lightweight strength while blocking up to 95% of UV and about 90% of visibility for cooling and privacy.
• All-Season Outdoor Use: Designed to reduce sunlight heat in summer, limit overnight frost effects, and shed light rain for versatile year-round coverage.
• Custom Sizes Available: Locally made to order so the canopy can match nonstandard patio, pool, or carport footprints with reliable lead times.
• 3-Year Limited Warranty: Backed by a warranty that offers added peace of mind for long-term outdoor use and durability.

Who It's For

This shade sail suits homeowners, renters with permission to anchor shade hardware, and small businesses that need a large, effective sun barrier for patios, pools, driveways, or carports. The tailored sizing and curved-edge design are especially helpful when a tight, neat appearance matters for entertaining areas or when matching a specific structure is required.

Those who should look elsewhere include buyers seeking a lightweight, temporary pop-up cover or an opaque waterproof awning; this sail offers light rain protection but is not a fully waterproof canopy and requires proper anchoring and some installation effort.
