plastic corner joint for window screen

A handy person from colorado says:
plastic corner joint for window screen that is 1/4 wide and approx one inch long on each are of the corner. It was about 15 small "fins" on each arm to grab or create a friction fit when inserted into the mitered metal frame corners. In the attached photo, the one on top is the part I am looking for and the one on bottom is a corner I found online but is too narrow.

This corner reminds me of our 95-131, but you should review our dimensions to ensure that they match up. Ours are a little bit more specific than what you've given.
