This top sash guide is from a window that was installed circa 2000. The label on the window is a Lawson SH-7500. My confusion is that the part #18-192 that you show is different than this part. Currently, I need 2 of these but I would like to have an additional 8 as backups.

Hello there!
I think our 18-201 may be a closer match for your top sash guide but review our dimensions to see what you think.
