We lined our side by side cabin for summer riding comfort. Use gloves and it sticks where you place it! ### ⭐⭐⭐⭐⭐ As advertised *by A***R on September 12, 2024* Easy to install and form. ### ⭐ Poor quality *by A***R on May 15, 2024* The first one I received was returned due to the same problem, the metal heat barrier separated from the fiberglass backing. The picture posted in this review is of the new one I received and has the same issue, I'll be gluing it back, not sure how long this will last. Very poor quality!! ## Frequently Bought Together - Design Engineering 50552 Black Floor & Tunnel Shield II 21" x 48" Adhesive Heat and Sound Insulation (7 sq ft) - Design Engineering 10039 1" x 15' Black Seaming Tape - Design Engineering 50549 Black Floor & Tunnel Shield II 42" x 48" Adhesive Heat and Sound Insulation (14 sq ft) --- ## 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.sk/products/240156896-design-engineering-50552-black-floor-and-tunnel-shield-ii-21](https://www.desertcart.sk/products/240156896-design-engineering-50552-black-floor-and-tunnel-shield-ii-21) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-20*
