Between my dining room and living room upstair area, there is one step down and there is a wall grille that is 5.5" tall.
What drives me nut is there is no 14x5.5 grille anywhere. There is either 14x4 or 14x6 grille wall / ceiling:
What am I thinking wrong? Or is this something 20 years ago that people don't make unstandardized size any more? Is this a custom made and/or should I cut the 14x6 to fit??
