Received the item as advertised and in due time. ### ⭐⭐⭐⭐⭐ Review *by A***R on 7 April 2017* This item worked perfect for me. It's much better than a solid duct. I used a 4" hole saw and the flexible duct will go through with no problems. When i tried to fit a solid duct through the same hole...not a chance. I purchased this for a bathroom fan and i;m very happy with it. Easy to pull and to make any necessary turn. The price was competitive as I tried multiple other web sites. ## Frequently Bought Together - TerraBloom Flexible 4 Inch Ducting - Black 8 Feet Flex Aluminum Duct with 2 Clamps – 4 Layer HVAC Ventilation Air Hose - Great For Grow Tents, Dryer Rooms, House Vent Register Lines - VIVOSUN D4 4 Inch 195 CFM Inline Duct Ventilation Fan HVAC Vent Blower for Hydroponics Grow Tent - EesTeck 4" (Diameter) Adjustable 304 Stainless Steel Duct Clamps Hose Clamp Pipe Clamp Air Ducting Clamp worm drive hose clamps (4Pcs, 91mm-114mm) --- ## 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.vn/products/345766830-flexible-4-inch-ducting-black-8-feet-flex-aluminum-duct](https://www.desertcart.vn/products/345766830-flexible-4-inch-ducting-black-8-feet-flex-aluminum-duct) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-03*
