Securing a shipping container isn’t just about picking a strong lock—it starts with a container built for security from the ground up.

At Secure-Rite, every container—new or used—comes standard with either a welded-on or bolt-on steel lock box, designed to shield your lock from bolt cutters, grinders, and prying tools. While some companies treat this as an upgrade, we include it from day one. Because we believe security should never be optional.

Why Shipping Container Locks Matter

Whether you're protecting tools on a job site, storing inventory, or safeguarding personal items during a move, the combination of a solid container and the right locking system is your first line of defense against theft.

Top Shipping Container Locks Ranked by Security & Use Case

Here’s how our top three high-security container locks compare—from most secure to most budget-friendly—along with recommendations on where and why to use them.

1. Master Lock Puck Lock 6271 — Most Secure Option

Best for: High-risk job sites, unsupervised areas, and industrial storage
Requires: Puck Lock Box (sold separately)

Why it's #1:

• Hidden shackle design leaves no exposed metal to cut
• Re-keyable high-security cylinder
• Extremely difficult to grind or tamper with when paired with our puck-style lock box

Important Note: This lock does not fit our standard lock boxes. To use it, you’ll need to purchase a compatible Puck Lock Box.

Ideal for: Construction companies, high-value equipment storage, or locations with minimal supervision.

2. ABUS Monoblock 92/65 — Best for Harsh Environments

Best for: Coastal areas, long-term outdoor storage, and high-moisture environments
Fits: Secure-Rite’s standard lock boxes (welded or bolt-on)

Why it stands out:

• NanoProtect™ coating resists rust and corrosion
• Thick, tempered steel shackle spins when locked—extremely hard to cut
• Precision pin tumbler core resists picking

Ideal for: Farms, seasonal storage, or anywhere exposure to the elements is a concern.

3. INSTA ProSeries 6850 Padlock — Best Value

Best for: Residential moves, short-term rentals, or lower-risk environments
Fits: Secure-Rite’s standard lock boxes

Why it’s still tough:

• Solid brass body with re-keyable 5-pin core
• Industrial-grade, tamper-resistant construction

Ideal for: Temporary or indoor storage, warehouse overflow, or when frequent re-keying is needed.

What About Twist Locks?

Twist Locks aren’t door locks—but they’re essential for stacking containers securely.

Twist Locks (Stacking Locks)

Function: Secure one container on top of another

• Made from heat-treated cast steel to handle heavy structural loads
• Common in modular builds, stacked storage, and container offices
• Not for locking contents—used strictly for structural security

Use twist locks to keep your stacked containers stable, and door locks to protect what’s inside. Together, they complete your security strategy.

The Lock Box Advantage

Every Secure-Rite container comes equipped with either a welded-on (new containers) or bolt-on (used containers) steel lock box.

Why it matters:

• Shields your lock from bolt cutters and grinders
• Conceals your lock from sight, adding discretion
• Built-in—no aftermarket installs needed

Need a different configuration? We also offer puck-style and retrofit lock boxes as accessories.
