horizontal sliding window track

Thanks for posting. I am afraid we only carry a limited number of sliding window tracks. In general this hardware is difficult to come by as many components are no longer made. Compare the 55-027, 55-028, 55-072 or 55-104 to your existing track and see if any match exactly. If none do, you're better off seeing if you contact whoever supplied the window for assistance. I am very sorry we cannot be of more help.
