A tip I used to make these work

These latches were not long enough for my application, the tip would not reach the openings in the window frame.

Just wanted to share what I did to make them work.

I cut the corner pieces down just inside the first hole in able to allow the latch to move further out towards the window frame. This worked for me although I may need a longer spring so the latches function the way they are designed to.

Right now I have to manually move the latches to engage the window frame, this is better than having no latches at all.

I also had to grind down the nub on the left side latch (the right side latch did not have the nub, although in the pic of the items it shows the nub on both latches)
