Since 2004, our patented return-air grille design combines style, versatility and performance. Engineered to ensure proper airflow and constructed to last for years. And our patented locking system provides a secure installation and simple operation for filter replacement, duct cleaning or inspection – all with no moving or visible hardware.

2-part design:
Each Premier grille is made from New Zealand pine and a super-strong 9-ply Baltic birch plywood louver frame. All are primed and ready to paint. Using superior craftsmanship with tongue-and-grove construction and glued at every joint, our grilles won’t warp, bend or break.

Each grille comes with a heavy-duty 26-gauge 3” deep metal frame that fits in your return-air opening flush to the wall without the need for tools or special skills. Just push it in and the outside flanges will prevent it from going too far into the return-air opening. Then just screw or nail it in like a metal return-air grille, insert your filter (if needed), and lock your grille in place with our patented locking system.

Choosing Your Size

All sizes are listed width by height (W x H). Please confirm before ordering.

The easiest way to choose your size is to use the same size as the 1" filter, if there is one at the return-air opening.

Our included metal frame has a 3″ depth and a width and height that are 3/8” larger than its nominal. For return-air grilles, the “nominal dimension” corresponds to the size filter and grille, neither of which are actually that exact size.

Our grilles require a 3/8" larger opening to accommodate our filter sleeve. If you have metal duct work you might NOT have the extra space and please reach out to us for our Architectural collection.
