I'm looking to "update" the look of my existing Andersen windows by adding grilles to the upper pane of my double-hung windows. My preferred grille style is the simple 4 square (rather than the traditional colonial 6 lite). It doesn't appear that Andersen offers that style.

Has anyone had any luck with aftermarket grilles that are made to fit standard size Andersens? I'm looking for white/white and would likely only do the front of the house (14 windows).

Thanks for any advice that you might be able to offer!
