Have you ever had a bug frame clip break off due to heat/sunlight degrading the plastic? This aims to replace that without changing the frame at all, its a clip-based aluminum bug screen pull.

This can replace broken plastic clips for window bug screens frames that are common in the USA. This is made for a 8mm width frame size, and it allows you to pull up on the frame so it installs correctly within the exterior and interior stops. It is small enough 1mm on each side to fit within most existing stops made for the 8mm aluminum frame.

Note: This is unlikely to be helpful for bug screen frames that use plastic friction screw to keep them in place.
