How To Measure A Grille

Overall Size: MEASURE the size of the DUCT OPENING. Do not measure the old vent cover.
If your duct opening is 14" wide by 20" tall, order a 14x20. Width vs Height The first number in a grille size, represents the width,
the second number represents the height.

Example: If your hole is 20" wide by 14" tall, order a 20x14. If your hole is 14" wide by 20" tall, order a 14x20.
