Lockwood 334C Series Shrouded Steel – The SCEC-Endorsed Security Shield
At Aus Lock and Safe Co, we know that high-security sites require more than just a heavy lock—they require a defense against specialized attacks. The Lockwood 334C Series Shrouded Steel Padlock is engineered for exactly that. By extending the heavy-duty steel case upward to form a protective "shroud" around the shackle, Lockwood has created a barrier that makes it nearly impossible for bolt cutters or prying tools to find a weak point.
This model (334C45/519) is a staple for Melbourne’s government facilities, infrastructure hubs, and high-risk commercial sites. It is SCEC Endorsed for intruder-resistant areas, providing a level of certified protection that standard padlocks simply cannot match.
Why Choose Aus Lock and Safe Co for High Security?
When you are dealing with SCEC-endorsed hardware, the installation and key management must be as secure as the lock itself.
-
SCEC Compliance Specialists: We understand the specific requirements for government and high-security sites. We can configure your 334C locks to be "Key Retained" to maintain their SCEC status.
-
Restricted Key Control: To complement the physical strength of the 334C, we recommend fitting it with a restricted cylinder like Lockwood Generation Six. This ensures that no unauthorized duplicates of your site keys can ever be made.
-
Local Industrial Support: Based in Laverton North, we provide on-site security assessments for warehouses and utility sites across Melbourne’s West, ensuring your hasps and chains are rated to match the strength of your shrouded padlock.
Pro Tip: Shrouded padlocks like the 334C are most effective when paired with a recessed hasp and staple. This combination leaves zero gap for a thief to insert a prying tool or a grinder blade, forcing them to move on to an easier target.
Features & Benefits
- Integrated Shackle Shroud: The solid steel body wraps around the shackle, shielding it from physical attack. If a thief can't reach the shackle with bolt cutters, they can't cut it.
- Chrome Molybdenum Steel Shackle: Features an 8.7mm shackle crafted from a high-tensile molybdenum alloy, offering superior hardness and resistance to sawing or cropping.
- SCEC Endorsed: When configured as "Key Retained," this lock meets strict government standards for use in high-security environments, ensuring it is built to resist professional-level tampering.
- Double Ball Locking: The shackle is deadlocked on both sides by high-tensile steel ball bearings, neutralizing "shimming" and ensuring the lock stays shut under extreme prying force.
- Convertible Deadlocking: Standard as a "Latching" lock, our technicians can easily convert it to "Key Retained" (Deadlocking) mode to meet safety or SCEC requirements.
- C4 Corrosion Resistance: The heavy-duty steel body and shackle are treated for high corrosion resistance, making it suitable for Melbourne’s industrial and coastal environments.
- 570 Cylinder Compatibility: Uses the industry-standard 570 oval barrel, allowing us to key it to your existing office master key or a high-security restricted system.
