The Abus 83WP/63C is a robust and weather proof closed shackle padlock that is capable of enduring the most volatile outside environments due to the 'NanoProtect' shackle. This is a chrome plating which protects the shackle from corrosion and therefore ensures reliability. The extreme range locks also provide first rate protection from physical abuse from various tools due to its hardened steel alloy body. This includes resistance to picking of the lock thanks to in-built top class anti-pick mechanics.
