Ooh climbing anchors sound fun. That’s got to be quite deep to hold any good weight in concrete. I only worked with static weight anchors - once finished there will be no change in weight or pressure at any given anchor.

To have concrete holes drilled that could hold a lot of weight shifting over and over seems like It mostly Depends on the anchor, since regular screws rarely hold anything over 5 kg reliably, and not when you jerk It around.

If you don’t mind, keep me updated! I’m intrigued.
