The material is not cheap, it's good quality. ### ⭐⭐⭐⭐⭐ Works as intended *by J***L on October 15, 2025* As advertised and no issues. Was using with hose for smoke machine. ### ⭐⭐⭐⭐⭐ Perfect fit! *by A***R on February 4, 2025* Got a120mm case fan and holes line up perfect on this 4-inch shroud/flange, so I would assume the same for the 92mm. It will be used for my small grow tent with 4-inch port for extra ventilation if needed. Glad I found this. Beats me trying to make something myself and nowhere near as easy to use. ## Frequently Bought Together - Coolerguys 120mm or 92mm Fan to 4" Ducting Shroud Funnel with Clamp for Greenhouses, Enclosures, Crypto Mining, and More - AC Infinity Flexible 4-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust - VIVOSUN D4 4 Inch 195 CFM Inline Duct Ventilation Fan HVAC Vent Blower for Hydroponics Grow Tent --- ## 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.us/products/333137581-coolerguys-120mm-or-92mm-fan-to-4-ducting-shroud-funnel](https://www.desertcart.us/products/333137581-coolerguys-120mm-or-92mm-fan-to-4-ducting-shroud-funnel) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-12*
