Measurement Guide
How to Measure for Replacement Registers and Grilles
Follow these measurement instructions for a snug fit.
• Locate the register or grille you are replacing and note if it is for a wall, ceiling or floor.
• Remove the screws that hold the vent in place. Pull the vent forward and out of the opening.
• Measure the size of the air duct opening. Do not measure the old register or vent. Note the measurements as width and
length as that is how they are packed and labeled.
• Ensure the new register or grille covers the opening. If the opening is large, look for units with wide borders.
