The whole fence is already manufactured and sitting in my yard ready to install, so I can't change the fundamental design. Just need to make up my mind about the bolts.
The fence is meters high above the pool. Below the pool is meters, (thus 3m long posts). I didn't think I'd have a problem with blow out, since the concrete is over 6 inches thick, and those anchor screws are recommended for near edge fixing. But now enough of you have mentioned it to have me thinking about that too now.
Seems the one thing everyone agrees on is an epoxy set system. Guess I can do that with a stainless stud so I don't need to worry about it rusting? I'd do 10mm studs with what, a 13mm or 14mm hole in the cleat for expansion?
