Not an easy install. *by B***N on Reviewed in the United States on March 22, 2020* First off, the product works when installed. That is fine. No instructions meant that I had to figure out how to install this lock. I have curved molding next to my door. I had to cut into it to create a deep, flat surface for the chain assembly to sit. Then I had to arrange the lock in a manner so it would lock easily. After some trial and error, I finally got both sides installed. As stated, it works. The screws are almost too short to hold in a hollow door. --- ## 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/87457772-security-heavy-ultra-thick-door-bolts-with-anti-theft-chain](https://www.desertcart.com.kw/products/87457772-security-heavy-ultra-thick-door-bolts-with-anti-theft-chain) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-16*
