590A Return Air Grille Nut - HVAC Vent Cover Replacement Part for Home & Commercial Use

I was afraid to buy this because I never buy anything without any reviews and I also don't like returning things plus it was pretty expensive for what it is. But I had gone to home Depot trying to find one of these and they said they don't sell them but that people ask for them all the time. Well I'm happy to report that my boyfriend just screwed this on to our return air grille and it fit perfectly he said it even fits better than the original. We have a standard return air grille. Ours is 20 x 25 x 1 as far as the filter size if that helps. but I have a feeling this would work on all different types of sizes.
