I am trying to install 4x4 wood posts to hold up a rectangular shade sail on my rooftop. The posts will be free-standing with nothing attached besides the sail.
Ideally, I would be able to attach them to the top of the half-walls. The top of the half wall is one layer of brick (that is covered in a little concrete or something) on top of cinder block. I think a 6-foot post will give me the right height, but I am worried about the brick breaking and the post falling 7 stories and killing someone on the sidewalk.
Please help me do this safely.
Use Simpson Strong Tie E-Z Base with a 1/2-Inch by 3-3/4-Inch Bolt Wedge Anchor for Cracked and Uncracked Concrete.
I also think I would have a back up cable attached to the wood and cinder block just in case, but I have literally zero experience in this type of installation. Below are pictures of my place. Any input is MUCH appreciated!
