This was easy to install but I recommend pre-drilling with a smaller bit so you don’t crack the door frame. This makes it easier to install too.The measurements are accurate, screws are sturdy, and the coating is holding up well after a month+ of frequent use. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great product *by C***G on Reviewed in the United States on November 23, 2023* Very nice quality and fit our door perfectly. Really helpful if you have a rough doorframe full of holes. It definitely made our lock more secure. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Bullet Proof *by S***9 on Reviewed in the United States on February 29, 2024* This additional steel plate really reinforces any door you install it on. Have one on the rear Garage door and one on the home’s Front door.Install was really easy, considering I have installed door plates of this kind in the past. Thief’s will have a tough time kicking these doors open… --- ## 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/572575995-nuk3y-sp550-combination-security-door-strike-for-5-1-2](https://www.desertcart.co.th/products/572575995-nuk3y-sp550-combination-security-door-strike-for-5-1-2) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
