Please add one notch charge for each grille that requires a sash lock notch.
Double Hung and Glider windows that have sash locks may require the grille to be notched so that it will fit properly if a bar falls at the lock location. We will notch one end of the bar to make the grille fit properly between the glass and sash lock.
If your window requires a bar to be notched, please provide the following information:
A = Sash Lock Height
B = Space remaining between glass and back side of lock
