Frequently Asked Questions
Can I use pool cover anchors for shade sails on wood railings?
Yes. Many pool cover anchors are brass deck anchors sized for 3/4" holes and work well for shade sails. Choose anchors with a collar to protect the wood and check that the supplied screws are long enough for your railing thickness.
Do I need special fasteners for thick or hollow railings?
Often you do. For thick railings you may need longer screws or through-bolts with a backing plate. For hollow railings use toggles or back plates to spread load and prevent the anchor from pulling through.
When should I choose a freestanding pole instead of anchors?
Pick a freestanding stainless pole when you can't or prefer not to drill into railings, or when you need taller, adjustable height and angle options. Poles require a sturdy base and are better for permanent setups or where the mounting surface is unsuitable.
