SQUIRE SS100 Stronghold Closed Shackle Dual Cylinder Padlock

The SQUIRE SS100 Stronghold Closed Shackle Dual Cylinder Padlock is engineered to provide extreme resistance against the most determined forced attacks. This ultra-heavy-duty padlock features a massive 100mm solid hardened steel body and a 20mm hardened boron alloy steel closed shackle, capable of withstanding a tensile pull of over 24 tonnes. To protect against harsh outdoor environments, the lock is finished with an electrophoretic coating that offers outstanding corrosion resistance.

Ideal for high-risk commercial premises, perimeter gates, and heavy machinery, this padlock is the first of its kind to achieve the prestigious Loss Prevention Certification Board (LPCB) SR4 standard. It features a unique dual-cylinder mechanism that provides advanced protection against picking, drilling, and sawing.

This padlock is available with different keying configurations, including Keyed Alike (where both cylinders operate using the same key) or Keyed to Differ (where each cylinder uses a different key). Please choose your preferred keying option, manufacturer reference (SS100CS or SS100CS/KD), and barcode from the options below.
