Our grilles can be installed in doors of any thickness as long as there are screws long enough. Screws that come in the box are just under 40 mm long (roughly 1 1/2 inch). I hope this answers your question. Regards, Engera Team. **Q: what is the net free area (NFA) of this grill?** A: Hi John, the NFA of this grille is approx. 0.015 sqm which is roughly 37% of the face grille area (calculated with the flanges). Hope this helps! Regards from Engera! **Q: Will this work on a pocket door with out causing opening and closing issues?** A: Hi and thank you for the inquiry. It depends on how the doors close/open. if they slide then it may not work if the gap between the door and the inside is too small as the grille is not completely flushed with the door surface.. Can you send us a picture of the door you have, we are happy to have a look and advise? All the Best Engera Team. **Q: I want to put these at the top of 2 bedroom doors. How would I install them and what could I put between them to block sound and keep air flow?** A: Hi and thanks for your inquiry. Always happy to assist, If this is for the natural ventilation (no mechanical - fan forced -exhaust system etc) then we are afraid that anything you will place to stop the noise transfer will affect th airflow, most likely making the whole process pointelss. if there is a mech system involved, then you can try to cut a piece of foam based air filter, similar to what is used in the vacuum cleaners to stop the noise whilst still making it all breathable. Note that depending on your fan capacity (static pressure) this may work satisfactory or less, depending on how tick is the acoustic layer and the relative fan spare capacity. No straight answer here, sorry for that. Acoustically the best solution would be to connect the bedroom with the corridor via in ceiling piece of duct and two ceiling mounted grilles. in terms of the installation, you make a cutout in the door and tight the two pieces together using screws which come with the grilles. hope this gives you some direction! All the best with your works! Engera Team! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Pay attention to install *by on Reviewed in the United States 21 April 2024* Its not the product's fault, it's mine. I wanted a vent at the bottom of our bathroom door since our 17 year old takes 45 minute super hot showers. The overhead vent fan couldn't keep up because the bathroom didn't get enough airflow. This was relatively easy to install, i'm not a woodworking pro. I took the door off and put in the garage. I traced the outline, started cutting. For those non-pros: use a saw that goes all the way through the door. When I got finished with my jigsaw, I realized it didn't make it through the other side, so I had to do a lot of work lining up and cutting from the other side. Oops. It still turned out great and works fine! Lets just enough air into the bathroom that our son doesn't create a water park. ### ⭐⭐⭐⭐⭐ Ventilación para puertas fácil de instalar *by on Reviewed in Mexico 5 May 2025* Llegaron muy rápido, empaque adecuado. Pedí e instalé yo mismo en 3 puertas.Usando el mismo molde con un plumón rayé la puerta, nivelado y centrado. Si incluye sus tornillos. 10/10. ### ⭐⭐⭐⭐⭐ Happy with these. *by on Reviewed in the United States 10 March 2026* My contractor says these were easy to install and they do not ding the looks of my six panel doors. Did not need painting on my white doors. ## Frequently Bought Together - Engera Bathroom Door Air Vent Grille Two Sided Ventilation Cover for Restroom, Warehouse, Storage Doors | Interior Door Transfer Grill 453mm x 91mm (18.1"x3.6") - INTERNAL VENTS Door Vent for Interior Doors 16 7/8" x 3" - Two Sided Door Louvers | for Bathroom, Cabinet | Plastic air Vent Grille | Outer Dimensions 17 3/4" x 3 5/8" for 16 7/8" x 3" Opening (White) - Vent Systems 1.5" Inch Pack of 4 White Door Air Register - Two Sided Door Louvers - Mini Circle - Ventilation Grille - Indoor Vent Grates - Bathroom, Cabinet, Garage Through The Door Vent Cover --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/250138737-engera-bathroom-door-air-vent-grille-two-sided-ventilation-cover](https://www.desertcart.tn/products/250138737-engera-bathroom-door-air-vent-grille-two-sided-ventilation-cover) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-11*
