GRANIT™ 37 Series – Ultra High-Security Padlock

ABUS GRANIT™ 37 Series – Ultra High-Security Padlock (All Variants, Professional Grade)

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.
