Screen parts
Thanks for reaching out to us! I'm sorry to hear that our 95-169 didn't work for you. Unfortunately, I'm not able to make a recommendation without seeing more of the original part. Would it be possible for you to remove an undamaged version of this corner so that I can see it without obstruction? Can you also tell me the precise thickness and depth of the frame itself? If the 95-169 is too big, then I need to know what size is correct so that I can find something better for you.
I'm afraid that's not enough for us to narrow it down. Without a brand name or a clear shot of the old corner to use as a reference, we have no data we can use to make a recommendation. At this stage you could have just about anything.
If you think you need a 3/8" corner then you can view our selection of that size here, but there is no guarantee that any of these parts will be a match. As you can see, even this one size has a pretty large array of different options and I really don't know if any one part would be better than the others.
I am sorry for the inconvenience. Your top priority at this stage should be to find some kind of solid reference. Without that, you're not going to be able to repair this screen.
