Squire Closed Shackle Stronghold Padlock

The Squire SS50CS and SS65CS Stronghold Padlocks are among the toughest padlocks available on the market. Manufactured in Britain and tested to CEN Grade 6, they offer the highest level of padlock security currently achievable, making them exceptionally resistant to bolt cutters, hacksaws, drills, and force attacks.

Built from solid hardened steel and finished with an electrophoretic coating, these locks are engineered for long-term outdoor use and have been chamber-tested to simulate more than five years of weather exposure. A hardened boron alloy closed shackle provides exceptional tensile strength and is shielded from attack thanks to the closed shackle design.

Both models include a 6-pin anti-drill cylinder with over 250,000 key differs, ensuring strong resistance to manipulation. A rubber base guard protects the lock body from water, grit and road salt, while the key-retaining function prevents accidental unlocking. Each padlock is supplied with two keys as standard.

While extremely weather-resistant, these models are not marine-grade and are not recommended for prolonged saltwater exposure.
