Lockwood Maximum Security 301 Series – The Industrial Hardened Standard
At Aus Lock and Safe Co, we recommend the Lockwood 301 Series for those who need a serious jump in physical security without moving to the massive monoblock designs. This 63mm hardened steel padlock is the "heavy hitter" of the standard-shaped range, offering an elite SP8 Physical Security rating. It is specifically designed to protect high-value assets in Melbourne’s industrial hubs—from shipping yards in Altona to heavy machinery sites in Truganina.
The 301 Series isn't just about bulk; it’s about high-tensile resistance. With a solid steel case and a thick molybdenum alloy shackle, it is engineered to withstand the most aggressive physical attacks, including drilling, sawing, and high-force cropping.
Why Buy from Aus Lock and Safe Co?
High-security hardware like the 301 Series requires expert configuration to ensure the keying matches the physical strength of the lock.
-
Restricted Key Integration: To maximize the SP8 rating, we can fit the 301 Series with restricted cylinders like Lockwood Generation Six or MT5+, ensuring your keys can never be duplicated without your authorization.
-
Keyed Alike Solutions: We can supply your site with dozens of 301 Series padlocks all operating on a single master key, streamlining your operations while maintaining maximum security.
-
Local Industrial Expertise: Based in Laverton North, we specialize in industrial security audits. We can ensure that your hasps, chains, and gates are rated high enough to match the strength of this lock.
Pro Tip: The 301 Series features a "Top Loaded" cylinder. This is a major advantage for maintenance; our locksmiths can service or re-key the lock from the top without having to disassemble the entire body, significantly reducing downtime for your facility.
Features & Benefits
- Hardened Solid Steel Case: The 63mm body is machined from heavy-duty, solid steel extrusion and hardened to provide a massive barrier against drilling and prying.
- 11mm Chrome Molybdenum Shackle: The shackle is crafted from a specialized molybdenum steel alloy, offering superior hardness and high resistance to bolt cutters and hacksaws.
- SP8 Maximum Security Rating: One of the highest ratings for a traditional shackle padlock, making it a favorite for commercial insurance compliance and high-risk site protection.
- Deadlocking Double Ball Locking: The shackle is secured on both sides by steel ball bearings, ensuring that "shimming" or pulling the lock open is not an option for intruders.
- Standard Key Retention: Configured as "deadlocking" (Key Retained), meaning you cannot remove the key until the shackle is fully locked. This provides a vital safety check for site managers.
- C4 High Corrosion Resistance: Features a high-quality chrome plating on both the body and shackle, designed to survive the fluctuating and often damp Victorian climate.
- Professional Rekeying: The top-loaded cylinder is compatible with the standard 570-style oval barrel. Our locksmiths can easily integrate this lock into your existing master key or restricted system.
