Hi,
The following photos are of an older bi-fold door missing the lower track for reinstallation, the photos include the manufacturer, the door itself and the bottom of the door. I have a few of these doors both 24" & 36" and I'm looking for the lower replacement track for all. I believe the 36" Low Profile Track Assembly, Product Code: 21-452 that I found on your site may be the correct one, but I would like assistance to be more certain before I order several. If there are further questions please call me.
Thank you,
Jocelyn
