Searching for 31164

I've never come across this corner before. We have a variety of nylon screen/storm corners that are similar, which you can see here, but none of them look like they're as big as yours. Can you confirm your dimensions? Please give me the thickness and width of the legs. Length doesn't matter, we just need thickness and width. Thank you!

I think I can help. Can you just double check your thickness? I think it might be closer to 3/16". Service technicians I've spoken to have successfully used our 95-054 as a replacement for your style of corner key.
