Review: Good replacement for my old diffuser - Works as a good replacement for my old diffuser. Holes match up. I posted on the Q&A inquiring about the distance from the center to the hole. I was skeptical about the answer and order one anyways. The answer was incorrect , the actual distance is about 6.25 inches. Review: They are plastic - I had a storm a tornado came through May 3rd and they forgot to put these up so I had to pay for these myself and I didn't realize I don't have to buy them I'm a woman so I had to buy the plastic ones and I didn't know those plastic cuz the other ones was metal but it doesn't matter they still do the job ## Features - Ceiling diffuser with all direction air deflection - Constructed with steel with step down structure - Powder coated in white with three matching color screws included - Listed size of 12" is for the duct opening measurement - Actual outside dimension is 16" ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08JXJNJHW | | Batteries Required? | No | | Best Sellers Rank | #183,397 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #556 in Tool Sets (Tools & Home Improvement) | | Color | White | | Customer Reviews | 4.3 4.3 out of 5 stars (179) | | Date First Available | September 23, 2020 | | Item Weight | 1.7 pounds | | Manufacturer | HBW | | Product Dimensions | 16 x 16 x 2 inches | ## Images ![HBW 12" Round Ceiling Diffuser White Powder Coated with Outside Dimension of 16" Fitting in 12" Duct - Image 1](https://m.media-amazon.com/images/I/81n6PqUizHL.jpg) ## Questions & Answers **Q: How do you connect a 12 inch diameter duct to the diffuser? (I know how to connect the diffuser to the ceiling).** A: This is just a cover, i.e. damper not included, so it does not connect to duct directly. Just mount to the ceiling surface **Q: How do you Connect the duct? Is there another part required?** A: No, just cover up the ceiling or mounting surface with included screws. **Q: How far is the distance between the screw holes?** A: about14“ **Q: Do you have these in 18"?** A: currently no.
