Better late than never

I made this sun shade for the pool equipment over a year ago. It works great until there's any wind in which case it becomes a sail and flies away (slight exaggeration). My previous attempts to combat this were to taking fishing string and tie it on or use zip ties to prevent it from flying away. None of those solutions worked very well. However, I think I have finally found the solution.


Here I drilled a hole and then put in a long screw so the pole can't fly away. However, there's still room in the back to lift it out if I need to remove it.


I did the same thing on the other side except this one you can't remove. You can also see my previous solution of the fishing string.
