The grilles were top quality. However, I bought grilles for my Anderson bay window. The grilles did not fit at the bottom of the window where the latch is located. The gap between the latch and the glass is only 1/8 of an inch. I had to cut down the grille so it would fit. I could have return the grilles but I decided to trim them so they fit. Also the grilles are wider than the originals. So if you have side by side windows, you should buy the pair so they match.
