I have Weathershield slider windows on my lanai. I was servicing them when a joiner piece broke. I see something that's very close, but mine has different dimensions than what I found on Swisco.com.
Do you have this one?

The joiner for the screen frame crossbar we believe you are looking at is our 70-006. It's smaller than your nylon piece, though, so I'm not sure if it can work. We also have the 55-184 grid clip, but it's also smaller. The only other solution I can think of, assuming these are too small to work, would be to drill holes in your nylon piece and install short nails to act like pins. What do you think?
Thanks for getting back to us. I'm not sure I understand your follow up post here. This information was also contained in your fourth photo from your original post, so it doesn't really change our assessment. Did you look over my response on the 2nd?
These pieces are called a ton of different things. We generally call them grid clips, but they're also called grille clips, retainers, or even pins.
