10 x 4 Steel Return Air Grille for HVAC Vent Cover

Ensuring the Proper Air Vent Size: A Guide

When ordering air registers and grilles, it is crucial to be aware of a few fundamental rules to guarantee you select the correctly sized vent the first time. These ventilation components are ordered based on the dimensions of the actual duct opening in the wall, floor, or ceiling that the vent will fit into or cover, not the overall size of the existing vent cover.

If you are ordering a wall return air grille or return air filter grille, it is important to note that these are directional. You must order based on the DUCT OPENING SIZE WIDTH X HEIGHT. This is particularly crucial if the grille is installed on a wall.

HORIZONTAL EXAMPLE: If the hole size is 24 inches wide by 14 inches tall, you would order a size 24x14 vent. VERTICAL EXAMPLE: If the hole size is 14 inches wide by 24 inches tall, you would order a size 14x24 vent.

To ensure you take the correct measurements, follow these steps:

STEP 1: Remove your existing vent cover, do not measure the existing cover. STEP 2: Measure the duct opening in your floor, wall, or ceiling. Record the LENGTH IN INCHES and the HEIGHT IN INCHES. This is your duct opening size. STEP 3: Match the duct opening size to the corresponding vent cover size listed on the product. The length and height of your duct opening should match the width and length of the specific register/grille.

It is essential to understand the following key terms:

Supply Register: A vent/grille through which air will blow out into the room, often with a damper on the back. Return Grille: A grille through which air is taken back from the room and into the return duct (sucked back into the wall). Return FILTER Grille: A hinged face that will open or swing down, allowing a filter to be placed in the back filter rack.
