Thieves using conventional methods will find the GRANIT CityChain XPlus 1060 a tough nut to crack. This is because the lock-chain combination is packed full of strong innovations. Patented ABUS Power Cell technology foils general attempts to remove the lock by hitting or pulling. A further security patent from us: the ABUS Power Link technology, which allows the chain to be directly connected to the Power Cell - the lock body.
