part that goes up the side of the casement window that allow

Hi there, Pat.

I'm afraid I don't know what it is that you're describing. Can you show us a photo of the part you're looking to replace? If there's an identical window in the house, we can use that as a reference. 

I'm afraid these photos don't tell me anything new. I can't make out the part in question, unfortunately. Would it be possible for me to see a clear and up close photo of the part you need to replace? 

Thank you for clarifying, Pat. It sounds like you're looking for a new tie bar. It's hard to say without seeing the whole thing but take a look at the parts we've related for you on this page. Review the specifications and see how they compare with your old tie bar. 

Great! I'm glad to hear it's a match.

As for replacement, it's not super difficult. You just detach it from the lock and unscrew the guides. That should allow you to pull the bar out and swap it with the new one.

You're very welcome, Pat. I'm happy to help! Let me know if I can be of further assistance and best of luck with the repair!
