Need Lock

Thanks for reaching out to us. It sounds like you may be looking for a version of this lock with a peg. I wonder if yours simply fell out. If that's the case, the 38-170 has a 1/2" post/peg. I recommend you compare the specifications with an undamaged version of your old lock to confirm.

I see what you mean. There could be two cases here. The first one being that the peg in your initial batch of photos (3rd photo) came out of the lock and is stuck. We recommend seeing if you can pull it out if you haven't already.

The second case could be that the peg is built into the lock bar which isn't something we've seen before. Unfortunately, we won't be able to help if this is the case. We don't have a lock that has a hole like yours. That isn't a configuration that we're familiar with so your best bet may be to contact the original manufacturer of the window, whoever they may be.
