Frequently Asked Questions
Do I need stainless steel or is galvanized cable OK?
For coastal areas or long-term exposure, 304 stainless fittings and cable resist corrosion best. Galvanized cable is cost-effective and fine for inland, seasonal use — choose thicker galvanized cable (3/16") for heavier sails.
Should I remove shade sails for winter?
If your area gets heavy snow, remove sails to prevent pooling and damage. In milder climates you can keep sails up but reduce tension slightly and inspect anchors and turnbuckles regularly.
How do I prevent cable clamp failure under heavy tension?
Use two clamps per connection oriented correctly, consider swaged sleeves or stainless thimbles, and tighten clamps with a proper socket. Inspect clamps after the first heavy wind event and replace any deformed fittings.
