Got window repair

Thanks for reaching out to us. I'm afraid I don't recognize this top sash guide at first glance. I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. 

It looks like you have the old PGT style top sash guide. We carry the new style, the 18-015, that should fit your window sash. Compare the specifications with yours and see what you think.
