White Plastic Perforated Tile/return with 1/2" Perforations, 100 Thick (#4994W-100-50)

Installed a suspended ceiling and needed a cold air return for the furnace/central air. This fits perfectly in the standard 2'X2' drop-in panel (actual size is 23 3/4" square). Just lift out one panel and put this in. Takes all of 30 seconds. Allows for plenty of return air and looks nice.

Bought it for the gym. ceiling. Our HVAC blower fan needed openings to suck the air that it could push down. This tile did the trick and it also looks pretty. I bought 4 of them and will be adding another 4.

The positives; they stop perfectly into place and look nice.Two small negatives; these are quite pricey, and don't seem to lend themselves to being cut into smaller sizes on account of their edges.

This worked exactly as the picture shows. I used it for venting a small foyer ceiling. When the wind blows, it would lift the tiles when the door was opened. No more issue. Great product.

Flimsy

It really does seem to be exactly 24 inch by 24 inch. Lets a fair amount of ventilation thru, which is why we bought it. Holes are big enough to see what is above, so if that is a concern for you, you'll need something different.Does what we want it to.

Perfect fit, very easy to clean. Couldn't be happier!

product did precisely what I wantedAllowed heat from lower level to rise through grill & heat wooden floor above.
