Durable Outdoor Protection – With zinc alloy body and hardened steel shackles

Zinc alloy housing resists corrosion while hardened steel shackles increase resistance to cutting and leverage attacks. Weatherproof and anti-rust treatments help the mechanism endure damp conditions.

Reliable protection for outdoor use, reducing deterioration in wet or exposed locations and extending service life.

Four-digit side-window design provides 10,000 possible combinations and a small resettable mechanism allows users to set a unique code. Large, high-contrast numbers improve visibility when dialling.

Simple to set up and operate for gyms, schools or workshops, removing the hassle and cost of managing keys.

Flexible Fit for Tougher Fixings – With long shackle design

Extended shackle length increases clearance for thicker hasps and awkward crossbars, while construction remains hardened for security. Supplied as a two-pack with a user manual for quick deployment.
