I'm trying to make my own casement windows to match other windows in my house. I understand the crank mechanism, hinge mechanisms, locks, and lock keepers, but on the hinge side of my existing windows there are these clips that come in pairs and I can't seem to find any reference to them when looking for casement hardware online.

I had thought maybe these were to pull the windows tighter against the weather stripping, but on closer inspection I don't think they make much contact when the windows close. Now I'm wondering if they're there to hold the widow in the event of wind loading, so the non-locking side doesn't blow out.

Picture is of the hardware I've got. I can add more pictures if necessary, but this is the best angle I think. The window actuators say Jeld-Wen, but I have no idea how old they are. I would guess probably 30 years, as the previous owners told me they last remodeled in the 90s. hinge pawls

Here's a zoomed-out picture. My pointer finger is in the groove for the window screen, middle finger is on the weather stripping.

I found them - they're called snubbers. From this site (no affiliation):

Snubbers prevent bowing of tall casement windows, or wide awning windows and have been found to be useful with double-hung windows in improving the seals of the bottom and top rails in the closed position.
