They fit the space just right and add peace of mind for protection from rodents that might want to invade a crawl space. Practical solution. ### ⭐⭐⭐⭐⭐ Awesome quality *by A***R on September 6, 2025* Awesome quality, I had to return because of the size. ### ⭐⭐⭐⭐ The Verminator *by G***G on March 10, 2024* I like that these stop the rodents from getting in, as the little buggers chew right through the screen in the vents. However, if you are are putting them inside the vent opening, most openings are roughly 16" x 8", so you'll have to cut them down to 8" high with a pair of metal cutting snips. If you're just covering the vent, you're good to go. --- ## 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.tn/products/1520435-tjernlund-950-8303-underaire-steel-crawl-vent-screen-18-x](https://www.desertcart.tn/products/1520435-tjernlund-950-8303-underaire-steel-crawl-vent-screen-18-x) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-30*
