I am not sure of the window manufacturer but the windows are about 12-13 years old. This trim piece fits on the outside face of the bottom edge of the lower sash sealing against the sill. I was able to find the manufacture name to be Simonson Profinish windows.
I hope this helps

Hi, thanks for reaching out with your well-done photo and measurements! I believe our 58-182 weather seal would work nicely for you. Look it over and let us know what you think. |
