Frequently Asked Questions
How do I measure my narrow patio to pick the right sail?
Measure the full length of the table plus seating clearance, then add 0.5–1 ft at each anchor point to allow for hardware and proper tension. Measure vertical clearance and aim for at least a slight pitch (one corner higher) to prevent sagging and help drainage.
Will these sails keep rain off my table?
These SUNNY GUARD sails are breathable HDPE that block UV and reduce heat but are not fully waterproof. Light drizzle may be shed, but heavy rain can pass through the fabric. For guaranteed waterproof protection choose a purpose-built waterproof awning.
Do I need special hardware to install on a narrow patio?
Basic ropes and D-rings are often included, but for narrow patios with limited anchor points or frequent wind, upgrade to stainless steel turnbuckles, pad eyes, and snap hooks for secure tensioning and long-term durability.
