⚡ At a Glance
  • Security Features: Patented anti-theft lock cylinder resists picking, drilling and cloned keys
  • Best for: Shipping containers, sheds, gates and garages requiring weatherproof high-security
  • Not ideal for: Users who need keyless or electronic access solutions

A heavy-duty padlock built from complex grade stainless steel with a patented anti-theft cylinder. High anti-corrosive properties and acid testing make it suitable for severe outdoor conditions.


High-level security - thanks to the patented anti-theft lock cylinder

The lock cylinder uses a patented anti-theft design that makes manipulation by picking, drilling and key cloning far harder than standard cylinders. Internal rings must align for the key to fully pass and rotate, adding a mechanical barrier against common forced-entry methods.

Strong resistance to tampering reduces the chance of break-ins. Suitable where higher protection against opportunist theft is needed.

Exceptional corrosion resistance - with complex grade stainless steel

Construction from a complex grade stainless steel delivers shock resistance and high anti-corrosive properties, proven by laboratory exposure to strong nitric acid for over 40 minutes. Design supports reliable operation even in severe freezing conditions.

Long-term outdoor exposure causes minimal rust or degradation. Ideal for coastal, wet or otherwise aggressive environments.

Built for industrial applications - thanks to compact, cut-resistant design

Shock-resistant materials and a form factor intended to sit inside shipping container lockboxes limit access to the shackle and increase resistance to bolt cutters. Rated to withstand over 4,000kg of force according to the manufacturer description.

Fits under 20ft and 40ft container lockboxes and works with tight-shackle applications such as gym lockers. Useful where space is limited but high mechanical strength is required.
