ABUS Granit 37RK / 80 padlock in check design and features

Even at first glance, the ABUS granite padlock 37RK / 80 signals that it is something special. The U-lock comes with a black coat, black black granite coating and silver GRANIT and ‘Made in Germany’ imprint. The ABUS logo is located in the lower right corner. The English word “Hardened” is stamped into the temple itself. Thieves and burglars know at first glance that cracking it will almost certainly take more time than a cheap padlock from the Far East. This is important because time is one of the most critical factors for this group of criminals. The longer an attempted break-in or theft takes, the greater the risk of discovery. The design of the ABUS granite padlock already increases the burglar protection.

An ABUS-Plus disc cylinder is used inside to protect against manipulation . Different disks are turned when the key is turned. The turning distance depends on the tooth depth of the key. If the discs are not in the correct position, a so-called blocking pin prevents the cylinder from rotating. The lock cannot be opened. Only when a suitable key has turned all discs into the correct position does the locking pin inside the ABUS granite padlock release the cylinder for rotation.

In addition, the cylinder inserted from above in the ABUS Granit U-lock 37RK / 80 offers protection against drilling and pulling . The lock is manufactured according to the European standard CEN class 5. A standard padlock, which z. B. corresponds to CEN class 2, for example, does not offer these features. In Germany, the requirements for padlocks are defined in DIN EN 12320. Here the ABUS Granit 37RK / 80 padlock corresponds to class 5. This is important if objects are to be insured against theft , such as a motorcycle, bicycles or a robotic lawnmower.
