We unfortunately don't sell a latch like you show here. I don't think I've ever seen this before, to be honest. Can you tell me what its function is? Would it also be possible to see what it looks like while installed?

There is a very good chance that we won't be able to get this for you, but I can try my best to track something down. I just need a little more context.

The peg locks the sashes together and also holds the balance in place. I replaced the two parts I purchased recently and happily the window slides up and down but because the lock on one side is broken it is only operating on one side. This window is very large and would be very expensive to replace. I took a picture but it is on my phone and I have to figure out how to send it to you.

The closest bolt lock I was able to find to your original was our 80-062. However, it's still very different and I do not know if it will be compatible with your window. I am sorry for the inconvenience.

thanks for trying / I had a feeling it was a lost cause but the parts I bought from you previously at least make my window operable which is a big help especially in the winter for keeping out the cold draft
