Very easy to install. They can be spray painted with enamel to match exterior, if preferable. Takes 30 seconds to install and I'm old. Genius idea! ### ⭐⭐⭐⭐⭐ Work Well *by T***X on November 1, 2025* If you haven't switched to automatic vent covers (which is the best) or just want some extra protection for your vent cover area during the cold months, these work well and are easy to install ### ⭐⭐⭐⭐ Good Product, Slow Shipping *by N***R on January 20, 2018* Installed 2 of these today as a trial. They fit my vents fine. It's a little tricky to install them, but I think by the time you did a few more it would be easier. Very windy today and they stayed in place through it all. Shipping from this supplier though was really slow. Might have to find them from someone else for that reason. UPDATE: These are still holding on well. I decided to order for the rest of my vents and found the exact same thing at Home Depot for 8.78 a pair and they arrived in 3 days. --- ## 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.co.th/products/66602168-gaf-master-flow-16-in-x-8-in-aluminum-foundation](https://www.desertcart.co.th/products/66602168-gaf-master-flow-16-in-x-8-in-aluminum-foundation) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-27*
