I'm trying to find an anchor similar this one, but one that's 10 inches wide since that's the diameter of my cedar logs. I want to use sonotubes and embed the anchor in the concrete as the logs are big and heavy.

I tried looking online, did reverse image searches and even asked chatgpt, but can't find anything similar. I'm guessing I'll have to talk to a local fabricator, but I'm not sure of how expensive that will be.

Any ideas? Thanks!
