What is this thing?

I have two of these devices that were installed in the skimmer entry when the pool was new. They are there presumably to provide support to the bull nose running across the top of the opening. Both of them have fallen out and I can no longer tighten them up. I'd like to replace them, but Ive got no idea what these things are called.

Pic below. What are these things called and where can I get a pair? thanks.

I have no clue. I googled "Pool skimmer parts diagram" and searched images instead of just the web. Hundreds of pictures, maybe you can spot your item
