We do not sell padlocks or U-locks separately with OKG heavy duty security chains. We plan to launch our OKG locks for sale in the near future, but it will take some time. In order not to affect your use, we recommend that you purchase ABUS, MASTER, Kryptonite and other brand locks to use with our security chain. We kindly recommend that you pay attention to the inner diameter of the lock and chain before purchasing a lock. Finally, thank you again for your support. BEST Regards, OKG Service Team **Q: Where/how do you carry this while riding your bicycle? It's heavy!** A: OKG security chain product comes with a zippered tote bag for easy portability。Chains locks are best carried wrapped around your seat post (although some brands sell bags that you strap to your frame). But it will increase your riding load. Make sure you've thought about this before you buy one. Is there room on your seat post? If not, is there room in your bag or your panniers? There are other places to put your lock when you're riding, but chains are more challenging than other bike locks. You use the mobile chain lock every day, carry it with you on your bike, and secure it around your bike and various street furniture in your neighborhood. Whereas a stationary chain lock will be left at home (or wherever you leave your bike overnight) and will only be used to secure your bike (or more likely several bikes) for an extended period of time. But what if you want both? Do you want a chain lock that you can carry with you every day and use overnight at home? Well, some locks can do both. But they didn't do well. How secure should your chain lock be? The best way to know security level of any bike lock, is to check the ratings from the independent testing house Sold Secure. All you need to know here is that Sold Secure test and measure bike locks according to their security level, rating each one Bronze (least secure), Silver, Gold or Diamond (most secure). OKG noose security chain has passed the Sold Secure product security evaluation with a rating of Gold. I hope the above information can be helpful to you, thank you for your question! **Q: what country is this chain made in?** A: Our OKG security chain is 4 ft/1.2M,12mm (1/2 inch) and it originates from China. OKG are a professional manufacturer of traffic locks and security chains. Our products have passed ART and Sold Secure test product certification. This security chain's resistance to shear, torsion, tension, and salt spray test meets the UK SOLD SECURE certification and the certification level is GOLD. **Q: Can magnet stick to chain ?** A: OKG security chains are made of special alloy steel which has been heat treated. Its main components are iron, chromium, titanium, manganese, vanadium, nickel, copper, zinc and other metal elements. Therefore, it is magnetizable. As a good performance carburized steel with high hardenability, it has a hard and wear-resistant surface with a tough heart after carburizing and quenching, and has a high low temperature impact toughness. It is the optimum choice as a motorcycle lock chain and generator security chain. ## Frequently Bought Together - OKG Ultra Security Chain - 4ft x 1/2in (12mm) Thick Hardened Alloy Steel Cut Proof Chain - Anti-Theft Heavy Duty Chain for Motorcycles, E-Cargo Bikes, Trailers, Gate Fences, and Garage Security - OKG Ultra Secure Stainless Steel Lock - 3 Keys, 2 Rods, Heavy Duty Solid Cast Padlock - 7/16" Shackle, Push Cylinder, Rust Proof Outdoor Lock - Combo Security Chain for 2-Wheeled Vehicle (No Chain) - OKG Heavy Duty Security Ground Anchor, 9/16" (14mm) Thick Hardened Steel Swing Shackle - Ideal for Bicycle Anchor, Motorcycle Anchor, E-Bike Anchor, Generator Anchor Lock - Permanent Anchor Point --- ## 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.be/products/290432525-4ft-noose-security-heavy-duty-chain](https://www.desertcart.be/products/290432525-4ft-noose-security-heavy-duty-chain) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-12*
