PERMA-LITE FINGER LATCH

Thanks for posting. We have many latches that could possibly replace this, but I cannot tell what you have from this photo. Would it be possible to see it removed from the storm window? Can you also give me more detailed dimensions? I suspect that this is a corner-type latch, which means we will need to know the thickness and width of the corner leg. In the meantime, you can see our entire selection here.
