Stainable Architectural Series A/C Return Grilles

Rated 5.00 out of 5 based on 2 customer ratings

These stainable grilles may have some inconsistencies in color and are therefore suitable for dark staining only. If you require a lighter stain, consider our made-to-order Design Series grilles  that are available in a variety of wood species and that have limited to no inconsistencies in color or grain variation.

Since 2004, our 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 a simple operation for filter replacement, duct cleaning or inspection – all with no moving or visible hardware.

2-part design:
Each Architectural Series grille is made with quality solid Poplar wood, however, custom grilles are available in any wood species required. Our premium grilles have large pores which stain beautifully, but are best suited for light stains. If you desire a darker stain finish, we recommend you request a specific wood species. Additionally, you will note 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 3” deep metal frame that fits in your return-air opening flush to the wall without needing 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). The easiest way to choose your size is to use the same size as the filter, if there is one at the return-air opening. The included metal frame has a 3″ depth and a width and height that are ¼” larger than its nominal size. For return-air grilles, the “nominal dimension” corresponds to the size filter and grille, neither of which are actually that exact size.

For instance, our 20×30 grille comes with a metal frame that holds a 20x30x1” filter and has an exterior dimension of 20-1/4” W x 30-1/4” H. A typical return-air opening will be sized 20-1/2” W x 30-1/2” H.

All Stainable Architectural Series A/C Return Grilles are Made-to-Order and have a lead time of 3 – 4 weeks. They are non-returnable and non-refundable.

    I can’t believe i just heard of these alternatives to metal vents. So happy to have an easy fix. Plus, changing my filter is easy.
