A Standard Stamped Face for Wall and Ceiling Returns
Flat stamped steel return grilles cover the most common wall and ceiling return openings with a one-piece stamped face and fixed fins. Within theSteel Return Grillesrange, the flat style is the standard, no-frills choice for returns that do not need a filter or a specialty shape. The stamped construction keeps the face rigid without a damper or moving parts, since a return grille only needs to let air pass back to the system. Most replacement jobs match this style first before checking filter or baseboard styles.
Sizing Range and Fixed Fins
Flat return grilles cover the widest sizing range in the steel return line, with widths and heights each running from4 inches to 32 inches. That range covers both small closet returns and large central returns in a single style. The fixed fins run at a set angle across the face, so airflow direction is not adjustable the way a supply register's blades can be. Once the opening size is confirmed, the color is the remaining choice.
Sizing, Colors, Bulk and Custom Orders
Flat return grilles are ordered by the duct opening, measured width by height, never by the outer cover. Both dimensions run from4 to 32 inches, covering small and large return openings in the same style. For return openings that also need filter access,Return Air Filter Grillesadd a removable or hinged door to the same sizing range. Bulk pricing spans6 quantity tiers, from 1 unit to 100+, with savings up to30%at the higher tiers. Orders of500+ unitsqualify for custom production depending on size, color, and lead time, and in-stock items ship the same day on orders placed by11AM ET.

GREAT Value and Price compared to box stores - works great as a fake cold air return
This is heavy duty, very nicely priced, and packaged perfectly. I looked at box stores and they were $4-5 higher each. Glad I looked here first. Also make sure you measure your space. I did, but in my quest for replacements, 14x6 actual size varies quite a bit each direction as much as 1/4 inch or more....Also yes the screws are included and they are matched to the color. I used these to cut holes for fake vents in the ceiling under the toilet and shower drains to prevent drywall damage. As in if they leak, it will drip out of the vent rather than sitting on top the drywall and messing up the ceiling. No one is the wiser, because it looks like a cold air return. These fit perfect between the floor joists.
The quality is excellent, and the installation was quick and straightforward. Shipping was fast and secure, and the item arrived in perfect condition. It looks great, take a look at the before and after pictures. I was able to find the exact size I needed at a much better price compared to Lowe’s. Very happy with this purchase!
I needed to allow air from the kitchen into the back room because it’s not heated and this worked perfectly! Just cut 2 rectangle holes in the wall - on both sides above the door, and screwed them right into the plaster-lathe wall… very easy!! Highly recommend!! Not flimsy and easy to fit where needed! Looks perfect!
The product itself, the grill, does what you think it does. Finish is pretty good and the manufacturing precision is fine for a standard house. I am removing a star each for the packaging and the included screws. The corner guards on mine were all busted up because they were apparently made of a brittle plastic. So I had to bend the corner metal back into shape on one corner. Several of the screws were curved such that they could not be driven with any force. Additionally the white paint is gooped onto the screws thick enough that a standard phillips does not fit into the recess and a standard socket hex does not fit around the outside. I eventually mined my own collection for screws.

Order by the duct opening, not the faceplate. Remove the vent and measure the hole behind it, then order that size. Getting it right the first time means no returns, no reorders, and no waiting on the job.
