Magpie 70mm heavy-duty,high-security padlock

Understanding “70mm heavy-duty Keyed Padlocks”

When searching for “Magpie 70mm heavy-duty keyed padlocks,” it’s important to clarify what you’re looking for, as the term “Magpie” can refer to different types of locking devices.

Decorative/Vintage Locks

First, some results might show small, decorative “Magpie Flowers” padlocks. These are often designed in traditional Chinese styles and are primarily used for jewelry boxes or small cabinets. However, these are typically not high-security items; instead, they are valued more for their aesthetic appeal.

Smart/Digital Locks

Second, there’s a brand called “Magpie” that produces smart digital door locks, such as the “Magpie – Black” model. Conversely, these are advanced keyless entry systems and are not traditional keyed padlocks.

70mm heavy-duty Keyed Padlocks (General Description)

Therefore, if you are looking for a “70mm keyed padlock” under the Magpie brand, you are likely seeking a substantial locking device designed for moderate to high-security applications.

Size and Use

To begin with, the “70mm” refers to the width of the padlock body, making it a fairly large and robust padlock. Consequently, this size is typically used for securing:

• Sheds
• Garages
• Gates
• Storage units
• Commercial installations
• Heavy-duty chains

Keyed MechanismFurthermore, a keyed mechanism means the padlock requires a physical key to unlock it. Within this category, you’ll find two main types:

• Keyed Different: Each padlock has its unique key.
• Keyed Alike: Multiple padlocks can be opened with the same key, which is useful for convenience when managing several locks.

ConstructionRegarding construction, the body is often made from hardened steel, solid brass, or zinc alloy for strength and resistance to cutting and prying. Additionally, the shackle—the U-shaped bar that goes through the item being secured—is usually made of hardened steel or boron alloy steel to resist cutting, sawing, and grinding. Moreover, some designs might feature a “discus” style, where the shackle is largely enclosed within the body for added security against bolt cutters.

The locking mechanism typically features a pin tumbler or disc detainer cylinder. Moreover, higher security padlocks will have more sophisticated mechanisms to resist picking, drilling, and bumping. Some may even include a double ball bearing locking mechanism for enhanced security.

Security Features

In terms of security, good quality 70mm padlocks commonly include:

• Anti-pick/Anti-drill cylinders: Designed to resist manipulation attempts.
• Hardened shackle: To prevent cutting.
• Corrosion resistance: This is especially important for outdoor use, with materials like stainless steel or brass, or special coatings, helping to prevent rust.
• Drainage holes: For outdoor padlocks, these allow water to escape, preventing internal corrosion and freezing.
• Non-duplicate-able keys: Some higher-security padlocks come with keys that can only be duplicated by authorized locksmiths or with a specific key card.

Typical Use Cases

Ultimately, due to their size and robust nature, 70mm keyed padlocks are chosen when a significant level of security is required for valuable assets or to deter determined intruders.
