What is the World's Strongest Padlock?

Discover the Unrivaled Security of the Squire SS100CS Padlock

What is the SS100CS?
The SS100CS, a famous flagship member of the Squire Stronghold® range, is the epitome of padlock strength. Engineered with a closed 20mm hardened boron alloy steel shackle and an ultra-secure dual key design, it boasts over 240 years of heritage in crafting formidable defenses.

Security Level of the SS100CS
The SS100CS has undergone rigorous in-house and independent attack testing, earning it LPCB Level SR4 and CEN 6 Plus approvals. When used in tandem with a 22mm security chain, such as our Behemoth Padlock and Chain Set (SS100CS/TC22/5), it's also granted the prestigious Sold Secure Motorcycle Diamond approval. These accolades mean it can withstand dedicated attacks from angle grinders, drills, and hammers for over ten minutes.

Key Features of the SS100CS

  • Closed 20mm hardened boron alloy steel shackle
  • 100mm wide solid hardened steel lock body
  • Accredited to LPCB Level SR4 and CEN 6
  • Two 6-pin cylinders, configurable as keyed alike or keyed to differ
  • A staggering 625 million possible key differs
  • Electrophoretic anti-corrosion finish
  • Storm-proof anti-corrosion cover
  • Anti-drill protection
  • Protective dust cover
  • Supplied with 4 keys (2 for each cylinder)


Benefits of the Dual Key System The dual key system of the SS100CS provides double the security against theft. With two 6-pin cylinders, offering a total of 625 million potential key differs, picking this imposing padlock would be an arduous task even for the most skilled burglars. Additionally, it can be configured as keyed alike, master keyed, or keyed to differ, catering to various security needs.

Manufacturing Process Crafted in our UK factory, the SS100CS undergoes stringent quality checks at every stage of production. 

Cutting Resistance The 20mm hardened boron alloy steel shackle is incredibly tough to cut through, making the SS100CS a formidable deterrent. In fact, it's often easier for thieves to target what the padlock is securing, think about that!

Security Chain Pairing For optimal security, we recommend pairing the SS100CS with a robust 22mm security chain. This combination yields a Sold Secure Diamond approved padlock and chain set. Consider the formidable pairing known as the Behemoth Padlock & Chain Set, featuring a 1500mm long hardened alloy steel chain, thoroughly tested against attacks, with numerous security accreditations.

Versatile Applications The SS100CS excels in providing robust security at home or work. Whether safeguarding industrial or offshore facilities, warehouses, gates, or high-security doors and perimeter access points its heavyweight design can endure serious sustained attacks. This makes it an ideal choice for low-traffic or remote areas where thieves have time for dedicated assaults using power tools.

Is the SS100CS the World's Strongest Padlock? With a legacy dating back to 1780, Squire continues to innovate and develop tough security solutions to combat theft. The Stronghold SS100CS, our most potent padlock to date and the first to achieve LPCB Level SR4 accreditation, proudly holds the title of the world's strongest production padlock.
