Old Sliding screen door

Hi there!

I'm afraid I don't recognize this part at first glance and I'll need a bit more information. Could you detail what it's function is and where does it install? Is there more to this part? If so, we'll need to see the rest.

Thank you!

I'm afraid we can't say for sure that this is what you have. We'll need to see an undamaged version, if possible, or we'll need to know some more information about the function and where it installs.
