XUNTING Heavy Duty Bike Chain Lock Anti-Theft Steel Chain with Nylon Sleeve 360° Rotating Lock for Bicycle E-Bike Motorcycle
Aliexpress UK
I believe this is a motorbike security chain (the kind used to wrap through a wheel and onto something) but we bought it to secure bicycles to a motorhome bike rack. Only used for that one trip. Comes with three keys. Length is 88cm and each link is nearly 3 inches (see image). As I said, used only once and has sat in a box since. Only visible sign of use is slight weathering of the brand name on the exterior sheath. Note this is heavy duty and weighs a fair bit for its length. Any questions, just ask.
