Maybe you could try removing the gasket and wrap a strip of fiberglass in it’s place. **Q: Would this help keep out bugs?** A: Yes it creates a barrier and only opens one way from the inside of house **Q: Would this fit between two sections of standard, 4 inch semi-rigid ducting? Looking to add to bathroom vent fan ductwork.** A: Yes, that's exactly how you would use it. Make sure to buy the correct HVAC aluminum (metallic) duct tape for the connection. A clamp cannot be used bc the crushing pressure would inhibit the flapper from working properly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Highly recommended! *by X***U on 4 April 2026* ### ⭐⭐⭐⭐ Grab some hvac tape, slightly undersized. *by M***N on 4 January 2026* ### ⭐⭐⭐⭐⭐ Well built *by E***T on 23 February 2026* ## Frequently Bought Together - 8 Inch Draft Blocker Backdraft Damper Duct Draft Stopper One-Way Airflow Ducting Insert Backflow Preventer Inline Fan Vent Deflector - V2262-50 7 Inch Bathroom Exhaust Fan, 50 CFM, 1.0 Sones, 7" Ceiling Exhaust Fan, for 8 Inch Diameter Rough-in Opening, Ideal Ventilation for Bathroom, Laundry Room, Mobile Home, Kitchen & Garage - Broan-NuTone 505 Exhaust Fan, White Vertical Discharge Ceiling Ventilation Fan, 8.5 Sones, 200 CFM, 8" --- ## 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.mx/products/531566054-8-inch-draft-blocker-backdraft-damper-duct-draft-stopper-one](https://www.desertcart.mx/products/531566054-8-inch-draft-blocker-backdraft-damper-duct-draft-stopper-one) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-05-08*
