What To Know Before You Buy
The chain is described as 6mm thick and 90cm long, so it is worth checking that this size suits your frame, anchor point or storage setup before ordering. The lock head diameter is listed as 1.06 inch, and the chain can be wrapped around an item if it cannot pass through a tight gap.
Pros: Two ways to unlock give you an extra option if you forget the combination, and the included carabiners add a little more everyday usefulness.
