the anchor bolt if installed correctly is very strong www.thestructuralworld.com/2018/04/15/anchoring-to-concrete/ It does depend what you mean by heavy wind though? In my installation the cable will snap before the bolt come out from the wall which is my safety measure, its about 500kg rated rope wire.

Hi, thanks for the clear instructions. Very helpful indeed. How about the brick wall? Is it double brick? Mine is brick veneer. Im worried if it can withstand certain amount of horizontal pulling?

@@ianzk1 Mine is a brick facade which is one brick, not a double brick. I think if you do it per his instructions it will work plus with the anchors he used. I am going to do it. I got to thinking and reasoned that for it to fail the brick and mortar would have to give way for it to fail in that brick. I do wonder if his brick is solid unlike mine that has the holes on the inside? I'm still going to try it. if it fails I have extra brick. You only live once. :-) Now, if you were going to be jumping in the middle of a sail, probably not. HA.

@@xsteel3292 Thanks! It's comforting to know that there's two of us trying it on brick veneer. If it the brick pops out, I'll just replace it as well. I'll be using M10 eye plates in combination with 8mm turnbuckle, 8mm D shackles, and 8mm snap hooks. I'll probably use 4mm wire ropes. My shade sail is 5.4M x 5.4M. We'll see how it goes.

@@ianzk1 How is your sail holding up? I am about to put one up. It will be attached to the rear brick wall of my house. Technically it is a facade (I'm pretty sure they are hollow bricks). Mine will be 15' x 20'. I was planning on attachments every 5' (that will be 5 across the long span). I am thinking that will spread out the horizontal load enough. Maybe I could go with 3, don't want to overkill.
