This 16mm premium hardened steel chain is guaranteed impossible to bolt-crop by hand.
A multiple award winner over many years, the high-quality material and our heat treatment process mean it beats other chains in magazine tests.
This 16mm thickness is one of our best-selling products, due to its price-to-performance ratio. It's a heavy beast - at 4.5kg per metre - so best used for location-based security (home or garage). Unless you've had your Weetabix, it is not very portable.
It offers excellent resistance to common attack methods and has been independently approved by the experts at Sold Secure to Motorcycle (Powered Cycle) Gold standard. It also meets the Secured By Design police preferred specification.
