Hi, I think its Product Code: 39-172..but not sure. This house was built year 2000, in case that helps...and if you zoom in, it just says "Truth", but no serial number.
I would like to purchase a few of these if it fits my windows.
Thank you

Hi there!
I'd say our 39-317 and 39-318 look like a closer match but review our dimensions and compare them to yours to see if you agree.
