Notched Corner for Top of Malta Screen

My Malta screens hinge at the top by fitting a notched corner piece over a peg on each side the just from the window frame. The corners you show here look like the ones that don't hinge at the bottom of the screen. Attached is a pic of what I have. The bottom of the screen simply attach via a Malta Screen Frame Latch.

Hi Tom,
That is the correct size for top and bottom but the top ones need the notch (left and right handed) as pictured. Do you have those?
