Not sure of brand. Windows installed 20 yrs ago. looking for corners, locking tab, and "D" shaped pull-out tabs that are on bottom.

Thanks for reaching out to us. Your screen turn clip looks like our 70-211, but your corner isn't made anymore. I would say the best option we have for that is our 95-002, which is 3/16" x 3/16". Look these two parts over and see if you agree.
