How do you determine the length of the steel cable if the anchoring point is further away. Is it the length of the turnbuckle fully extended plus the distance you want to cover with about a foot to fold over the eyelet?
Hi! Thanks for your question. If I'm understanding correctly, you're looking to use a tether cable with your Custom Shade Sail. The best way to do that is to measure between the eyelet locations, then tell us how long you want your tether cable to be (best if it's not more than 10-feet). We'll then design the sail to fit within your dimensions and using your tether cable length to fully tension the sail! For further discussion please send us an email at info@shadesailscanada.com
