Common questions
Right Triangle Shade Sails FAQ.
Is the right triangle shade sail size the fabric size or the post-to-post size?
Stock sizes are measured D-ring to D-ring on the finished sail. Your posts or wall anchors should sit farther apart to leave room for hardware and tension — plan roughly 10% of each side (at least 12″) at every corner. The planning guide walks through it.
What comes with the sail?
Each stock sail has reinforced corners with stainless D-rings, a sewn perimeter hem with pre-installed 3/16″ stainless wire rope, and UV-stabilized thread. Choose a turnbuckle kit, a 4:1 pulley kit, or sail only.
How long until it ships?
Every sail is cut and sewn to order in Phoenix. We confirm your ship date when we confirm your order, and rush production is available — call if you have a deadline.
What if my space isn’t a stock size?
Most spaces aren’t. A custom sail is cut to your exact anchor points and usually tensions better than forcing a stock size to fit.
Can I return a sail?
Because every sail is made to order in the color and size you choose, returns are limited. Please double-check your measurements and color before ordering — we’re happy to review them with you by phone.

Not a stock size? We’ll cut one that is.
Send your anchor-to-anchor measurements and a photo — custom sails are often only a little more than stock and fit far better.
