Read some reviews that people had found this rattling a bit when in the vent hose but haven't found these issues for us. Works well and significant drop in the cold air coming in through especially during windy and cold winter days. Worth the money for a quick DIY fix. ### ⭐⭐⭐⭐ Good,not perfect. *by T***L on 15 February 2020* It was fairly easy to fit, you do need to get some large jubilee clips. It does work, but there are problems, when we had some strong winds the shutter went "over centre" and jammed open. I put a small screw in to stop it going too far. When the shutter is open as much as it will go, there is still some restriction to the flow of air. It is a bit noisy when the wind is gusty, opening and closing. ## Frequently Bought Together - Kair Connector with Backdraught Shutter 150mm - 6 inch Non-Return Damper Flap to Connect Duct Pipe or Flexible Ducting Hose - Kair 90 Degree Elbow Bend 150mm - 6 inch Round Plastic Ducting Joint to Connect Round Duct Pipe or Flexible Hose - Kair Plastic Ducting Pipe 150mm - 6 inch / 350mm Short Length -Rigid Straight Duct Channel --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.om/products/50213535-kair-150mm-round-duct-connector-with-backdraught-shutter](https://www.desertcart.com.om/products/50213535-kair-150mm-round-duct-connector-with-backdraught-shutter) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-08-04*
