Abus 83/50 "The Rock" – The Big Brother of the 83 Series
At Aus Lock and Safe Co, when a client says the 45mm padlock looks a bit "light" for their heavy-duty gate or industrial shipping container, we move them straight to the Abus 83/50. As the larger, heavier sibling of the 83/45, the 50mm model offers a more substantial physical presence and a thicker shackle, making it the premier choice for high-value commercial assets across Melbourne’s industrial sectors.
It retains all the "locksmith-friendly" DNA of the Eighty-Three series—including the ability to be keyed to your house key—but wraps it in a beefier, nickel-plated brass body that commands respect from anyone looking for a weak point in your security.

Shackle Diameter 9.5mm

Horizontal Clearance 22mm
Security Rating AS4145.4 Physical Security: SP6

Features & Benefits
- Increased Shackle Diameter: Moving up to a 9.5mm special alloy shackle, the 83/50 offers significantly more resistance to bolt-cutter and sawing attacks than the smaller 45mm version.
- Nano Protect™ Technology: The shackle is treated with a high-tech coating that seals the steel against the elements. Whether you're in the humid north or the salty air of the Port of Melbourne, this lock is built to resist rust for years.
- Chrome-Plated Solid Brass Body: The 50mm body is machined from solid brass and then chrome-plated for an extra layer of protection and a clean, professional finish that suits any commercial environment.
- The Patented "Z-bar": Like its smaller sibling, it features the Z-bar, allowing our locksmiths to switch it from key-retaining (safety mode) to non-key-retaining (convenience mode) in seconds.
- Double Ball Bearing Locking: The shackle is deadlocked by two steel ball bearings, ensuring that "shimming" or prying the lock open is a near-impossible task for an intruder.
- C4/LW4 Keyway Compatibility: It uses the standard 6-pin 570-style barrel. This means we can key your padlocks to your front door, back door, and shopfront gate, so you only ever need to carry one key.
