ABUS 37RK Series Closed Shackle Granit Plus Padlock

The ABUS 37RK Granit Series the 37RK/60, 37RK/65 and 37RK/80 is one of the highest-security padlock ranges available worldwide. Built to Swedish insurance standards and tested to BSEN 12320 with CEN Grades 4 and 5, these locks are engineered for environments where cutting, drilling, torsion and extreme weather must all be resisted.

Each lock uses the ABUS Plus disc cylinder, a highly pick-resistant mechanism with 250,000 unique key differs, supplied with a code card for controlled duplication. Keys cannot be copied by standard locksmiths without the code, offering a partially restricted system for improved key security.

The hardened alloy steel body and shackle deliver outstanding tensile and cutting resistance. Combined with the closed-shackle profile, they offer maximum protection against bolt cutters, saws, grinders and levering attacks.

ABUS applies a specialist cataphoretic coating, delivering unmatched corrosion protection independently confirmed to last 40+ years outdoors, even in saline conditions. This makes the 37RK ideal for marine, coastal, industrial and exposed environments.

The shackle can also be converted to fully removable, allowing easier use in restricted spaces. The lock is key-retaining for added security, preventing it from being left unlocked by mistake.

Each padlock includes two keys, one of which features an integrated LED for night use.
