The Squire SS100CS is widely recognised as the world's strongest production padlock, achieving LPCB's highest rating SR4 making it the only standalone padlock to ever meet this standard. Built for extreme, high-risk environments, it combines a huge 100mm hardened steel body with a 20mm diameter boron-alloy closed shackle, delivering unrivalled resistance to cutting, cropping, drilling, freezing, sawing and sustained attack.
Two independent 6-pin cylinders offer over 625 million differs, with full protection against drilling, picking and bumping. The dual-cylinder design also enables supervised access applications where two keys may be required to operate the lock.
Designed to withstand all weather conditions, the SS100CS includes a storm-proof cover, corrosion-resistant treatment, and a sealed keyway cover to protect the internal mechanism.
This is the flagship of Squire's Stronghold range, engineered for environments where padlock failure is simply not an option.
