Lockwood Maximum Security 356 Series – The Heavyweight Industry Standard

At Aus Lock and Safe Co, we know that when it comes to securing industrial gates, heavy machinery, and perimeter fences, "standard" security just won't cut it. The Lockwood Maximum Security 356 Series is a 63mm powerhouse designed for environments where the risk of physical attack is high. Achieving a formidable SP8 Physical Security rating, it is the "Big Brother" to the 301 series, offering a thicker shackle and a more substantial body to thwart even the most determined intruders.

Whether you are protecting a construction site in Truganina or a transport depot in Laverton, the 356 Series provides the uncompromising strength of a hardened steel case or the extreme weather resistance of a stainless steel body.

Why Buy from Aus Lock and Safe Co?

A maximum-security padlock is only effective if its keying system is equally robust. At Aus Lock and Safe Co, we ensure your 356 Series is integrated into a complete security solution:

  1. Restricted Key Integration: We recommend fitting the 356 Series with Lockwood Generation Six or MT5+ restricted cylinders, ensuring no unauthorized duplicates can be made by staff or contractors.

  2. Custom Keyed-Alike Systems: We can supply your entire site with "Keyed Alike" sets, allowing one single high-security key to open every 356 Series lock on your perimeter.

  3. Industrial Site Support: Based in Laverton North, our Master Locksmiths provide on-site audits and maintenance. We can help you choose the correct shackle height and material for your specific environment.

Pro Tip: The 356 Series is exceptionally heavy. If you are using this on a gate that swings frequently, we recommend pairing it with a heavy-duty Grade 80 high-tensile chain. This ensures the chain is just as hard to cut as the 11.1mm molybdenum shackle.

Features & Benefits

  • Hardened Steel or Stainless Steel Options: Available as the 356S (Hardened Steel for maximum brute-force resistance) or the 356M (Marine Grade Stainless Steel for coastal and corrosive environments).
  • 11.1mm Molybdenum Shackle: The steel model features a massive 11.1mm shackle crafted from a specialized chrome-molybdenum alloy, providing elite resistance to bolt cutters, saws, and cropping.
  • Double Ball Deadlocking: The shackle is secured on both sides by high-tensile ball bearings. This configuration is "deadlocking" by default, meaning the key is retained until the lock is securely closed, preventing accidental "unlocked" states.
  • SP8 Security Rating: Tested to exceed Australian Standards (AS4145.4), this lock is built to resist drilling, prying, and high-impact attacks.
  • Top-Loaded Cylinder: The precision 6-pin cylinder (supplied as 5-pin) can be serviced or re-keyed from the top, making it an favorite for facility managers who need low-maintenance security.
  • 570 Barrel Compatibility: Uses the industry-standard 570 oval cylinder, allowing our locksmiths to key it to match your existing office, warehouse, or residential keys.
