⚡ At a Glance
- • Security Features: Tough-Cut octagonal boron-carbide shackle, 4-pin cylinder and dual ball bearing locking increase resistance to cutting, picking and prying
- • Best for: Securing storage units, garden sheds, garages, gates and outdoor fences where weather exposure is likely
- • Not ideal for: High-security commercial applications that require electronic or keyed-alike master systems
Laminated steel body with a weather resistant cover protects internal components. Covered keyway and shackle seals add further protection against corrosion.
Dependable outdoor protection - thanks to covered laminated steel and weather seals
A laminated steel core is encased in a weather resistant cover that blocks snow, rain, dirt, mud, grime and salt. Covered keyway and shackle seals prevent moisture and particles from entering the locking mechanism.
Corrosion and grime are kept out, so locking parts stay functional after prolonged outdoor exposure. Reliable operation reduces the need for frequent replacements or maintenance.
High cut and pry resistance - with Tough-Cut octagonal boron-carbide shackle and dual ball bearings
The Tough-Cut shackle is octagonal and made of boron-carbide, rated 50% harder than hardened steel, while dual ball bearing locking resists shackle-prying attacks. The combination increases mechanical resistance against bolt cutters and leverage tools.
Strong shackle and anti-pry locking make forced entry significantly harder, suitable for protecting valuable tools and equipment. Adds confidence when securing gates and external storage.
Smooth, reliable key operation - thanks to a 4-pin cylinder and included seals
A 4-pin cylinder enhances pick resistance and, together with a covered keyway, reduces exposure to grit and rust. Four keys are supplied to allow multiple authorised users without rekeying.
Keys turn smoothly with minimal sticking reported by users, even after outdoor use. Spare keys mean convenient access for household members or colleagues.
