Here at The Lock Source, we’re always looking for ways to bring you more choices, more value, and more protection. That’s why we’re excited to announce the newest addition to our lineup: American Lock products are now available!

That’s right—our already extensive collection of Master Lock solutions just got stronger, with the full catalog of American Lock now in stock and ready for both commercial and residential applications.

If you’re wondering what makes American Lock different—or whether it’s the right choice for your security needs—read on. We’re breaking it all down for you.

Master Lock vs. American Lock: What's the Difference?

At first glance, Master Lock and American Lock might seem like competitors. But here’s something you might not know: they’re both owned by the same parent company, Master Lock Company, and many of their products are manufactured in the same facilities.

So why two brands? Because each one is designed for different levels of use and specific applications.

Is American Lock Better than Master Lock?

Not necessarily “better”—but built for different purposes. Here’s how they compare:

🔒 Master Lock

• Ideal for residential and light commercial use.
• Widely used for lockers, gates, cabinets, and general-purpose security.
• Affordable and reliable.
• More commonly found in retail environments.

🛠️ American Lock

• Designed for heavy-duty, high-security commercial and industrial applications.
• Constructed with solid aluminum or brass bodies, making them more durable in extreme environments.
• Often used in utilities, government, transportation, and heavy industry.
• Features more customizable options (keying, shackle sizes, security ratings).

So if you’re locking up a toolbox, school locker, or shed, Master Lock is a great choice. But if you need tamper-resistant, high-security protection for a job site, fleet, or facility, American Lock is the way to go.

Why Do the Lock Shapes Look Different?

One of the first things you’ll notice is the shape of American Lock padlocks. Most feature a rectangular or squared-off body—unlike the more rounded bodies of many Master Lock models.

This isn’t just for looks:

• The shape and design of American Lock padlocks are made to reduce shackle exposure and resist tampering or cutting.
• The solid-body construction offers greater strength and resistance to corrosion, wear, and physical attacks.
• The shape often allows for more shackle clearance options, especially in custom applications.

When Should You Choose American Lock Over Master Lock?

Consider American Lock for:

• Industrial sites or warehouses
• Electrical panel or utility box lockouts
• Fleet or transportation equipment
• Harsh outdoor environments
• High-security commercial use
• Anywhere you need keyed-alike, master-keyed, or color-coded lock options

Stick with Master Lock for:

• Residential gates, doors, or sheds
• Gym or school lockers
• Small business or light commercial spaces
• Everyday locking needs at a lower price point
