Abus 83CS/55 "The Rock" – The Ultimate High-Security Fortress
At Aus Lock and Safe Co, we know that for some Melbourne sites, "tough" isn't enough—you need "impenetrable." The Abus 83CS/55 is the apex of the Eighty-Three series. By combining a hardened special steel body with a fully integrated shackle guard (Closed Shackle), Abus has created a padlock that effectively neutralizes the most common tools of the trade: bolt cutters, saws, and prying bars.
This is a serious piece of security hardware, weighing in at over 600g of solid, hardened steel. It is SCEC approved (SL3), making it suitable for high-level government and infrastructure protection, as well as any business owner who wants the peace of mind that comes with "The Rock."

Features & Benefits
- Integrated Shackle Guard: The "Closed Shackle" (CS) design features high steel shoulders that surround the shackle, leaving virtually no room for an intruder to apply bolt cutters or a hacksaw.
- Hardened Special Steel Body: Unlike brass models, the 83CS/55 is forged from specially hardened alloy steel, providing maximum resistance against drilling, grinding, and brute-force impacts.
- 11.5mm Special Alloy Shackle: The extra-thick shackle is treated with Nano Protect™ coating, offering an elite balance of extreme physical hardness and high-level corrosion resistance against the Victorian elements.
- SCEC SL3 Rated: This lock is endorsed for use in high-security government applications, confirming its status as one of the most secure padlocks available in the Australian market.
- Double Ball Locking Mechanism: The shackle is deadlocked on both sides by steel ball bearings. This ensures the lock cannot be "shimmed" or pulled open, requiring two full cuts of the hardened steel to bypass.
- Patented Z-bar Versatility: Our technicians can instantly switch the lock between key-retaining (where you cannot remove the key while the lock is open) and non-key-retaining modes to suit your workflow.
- Keyed to Your Front Door: It uses the standard 570-style 6-pin barrel. We can re-key this industrial powerhouse to match your existing house or office keys, giving you 4K-level security with "one-key" convenience.
