"What do I measure for a 4 Way Ceiling Grille?"
Our Square 4 Way Steel Ceiling Grills have a faceplate dimension of 23.75" x 23.75" so you want to make sure you measure the actual duct working in the ceiling when ordering. It's duct collar is 2 inches tall and that is what slips right into the duct work. Be sure to measure the duct work diameter. If your duct work measures 8 inches in diameter, you will want to order an 8 inch 4 Way Ceiling Grille.
