GRANIT™ 37 Series – Ultra High-Security Padlock

GRANIT™ 37 Series

The ABUS GRANIT™ 37 Series Padlock represents one of the highest levels of mechanical security available, engineered to withstand extreme physical attacks with a tensile resistance exceeding six tonnes. Designed for industrial, commercial, and high-risk environments, this series combines special hardened steel construction, a double ball locking mechanism, and the advanced ABUS-Plus disc cylinder for maximum protection against cutting, pulling, and picking.

Finished with a corrosion-resistant Black GRANIT™ coating and supplied with a security card to prevent unauthorized key duplication, the 37 Series is built for long-term outdoor and marine use. Multiple sizes, shackle types, and re-keyable (RK) options make it a highly flexible solution for professional security systems.
