ProVia storm door window latch 1.75 " from screw to screw center.

Question

The latch has a horizontal slide mechanism to keep the two panel glass storm pieces  in place when the top glass piece is up.  Otherwise the glass slides down and the screen rolls out.

Unfortunately, I'm not familiar with the ProVia brand. Would it be possible to see a picture of the latch in question? If this is for a storm window, I will also need to see the latch out of the window, if at all possible.
