Handua 24″W x 12″H [Duct Opening Size] Steel Return Air Grille (HD Series) Vent Cover Grill for Sidewall and Ceiling, White | Outer Dimensions: 25.75″W X 13.75″H for 24×12 Duct Opening

Step 1 – Remove Your Old Grille

Remove the screws that secure the grille onto the wall/ceiling. If this is a ceiling application, prevent the grille from falling down for your safety.

Step 2 – Take the Correct Measurements

Measure the Duct Opening (the hole on the wall/ceiling) by measuring the WIDTH first, and then the HEIGHT (e.g 24″ W x 12″ H), this is the size you should order.

• ONLY MEASURE THE DUCT OPENING
• DO NOT MEASURE YOUR OLD GRILLE!

ATTENTION: THIS IS A FLAT GRILLE, NOT A FILTER GRILLE

The product group you’re viewing at the moment is a Return Air Grille, NOT a Return Air Filter Grille. These grilles used for mounting on the wall directly (Screws included) and they don’t use any filter, don’t have an openin/closing door or a frame gets into the wall. Please see our other products if you need a Return Air Filter Grille.
