Long-term corrosion resistance - thanks to complex grade stainless steel construction

Body, shackle and cylinder are made using complex grade stainless steel which resists oxidation and surface corrosion. The material choice reduces the chance of seizing or rusting after prolonged wet or salty conditions.

Corrosion resistance keeps the lock functional through seasonal weather, reducing the need for replacements or frequent maintenance.

High theft resistance - with a patented high-precision lock cylinder

A patented, high-precision cylinder design makes conventional attacks—such as picking, drilling and prising—far more difficult by maintaining tight tolerances and internal ring alignment.

Enhanced cylinder security gives added peace of mind where opportunistic theft is a risk, particularly on exposed gates and outdoor stores.
