L-shaped clip for a Harvey window screen. Projection fits in the hole in screen, and slip is turned to secure screen. We need to replace a couple that have fallen out of the windows, and we can't find them anywhere.

Hello! See our 70-026. This appears to serve the same function as your clip. Could you use this as a replacement?
