Is it strong or brittle?** A: Hi, I tried to measure thickness with a ruler, it appears to be a little under 2mm thick. I also took a video to try to give you some idea of how strong it is. It is not completely rigid as it is slightly flexible but even if you push firmly it doesn’t show signs of being brittle of breaking. That said I haven’t pushed it with absolute force as if deliberately trying to break it! ## Frequently Bought Together - FANTRONIX 100mm Round Telescopic Wall Extension Sleeve Nested Pipes Exhaust & Supply Air Extractor Fan Ventilation 4 inch Round Duct Extendable Vent Tube - Blauberg Condensation Control Passive Wall Intake Vent Grille Cover 100mm (4 inch) Spigot White Mould Control - Kair White Louvred Wall Vent Grille 155mm External Dimension with Flyscreen and Round 100mm - 4 inch Rear Spigot --- ## 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.com.kw/products/319961891-100mm-4-inch-round-telescopic-wall-extension-sleeve-adjustable-ducting](https://www.desertcart.com.kw/products/319961891-100mm-4-inch-round-telescopic-wall-extension-sleeve-adjustable-ducting) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
