Screen corner keys ID

A quick learner from USA says:
Hi: I need some screen corners. Using your illustrations, it is not intuitive either how I need measure to determine the needed dimensions or whether what you have satisfies my requirement. the dimensions of the frame outside edge are 7/16" by 3/4". Thanks so much for your prompt response. I have attached a photo which I trust will help you appreciate me needs more clearly.

Thanks again, Thanks, Dan

Hey, Dan. It's hard to tell for sure but you may be able to use our 95-151 and 95-150 Malta corners. They look close to yours, and the dimensions are the same.
