Commercial vinyl window latch

The design of your latch is very similar to our 26-215. I think this may be what you want, though yours appears to have two flanges on the front end of the housing. I'm not sure if those are important for installation or not, but ours lacks that particular feature.

Otherwise, as long as our dimensions line up with yours then I think our 26-215 will work perfectly fine. You can review them below.
