EXTERIOR PADLOCK IN ULTRA-RESISTANT STEEL: This padlock is made of hardened steel to ensure the security of your belongings and deter burglars. It weighs 850g and measures L10 x W2.4 x H6.5cm. The shackle measures 12mm in diameter. When locked, the gap measures L3.9cm x H2cm. The ideal format for the majority of locks and latches. OPTIMAL SECURITY: Our key padlock weighs 850g, which makes it particularly robust. With its solid hardened steel structure, it is ultra-strong and durable. Each of our anti-burglary padlocks has a rotating shackle/closed shackle, which provides anti-drill and anti-cut locking. This master lock padlock has been ingeniously designed to leave no gaps. 4 KEYS INCLUDED: All our industrial padlocks are supplied with 4 keys, because you never have enough spare keys. Keep some in a secure place in case you lose one. You can also give one to your loved ones. The keys can only be removed from the padlock when it is closed. LOCK AND GO: Thanks to its unique D shape, this lock is the ideal solution for securing containers from 6 to 12 meters, as well as gates, garage doors, caravans and sheds. It can also be used as an anti-theft padlock to secure a motorcycle.
