Shipping containers carry valuable cargo across long distances and through multiple hands. That kind of exposure demands a lock that is more than just strong. It needs to be engineered for real-world threats.
Enter the Crab Discus Lock, a smart, compact, and powerful solution for protecting shipping containers, trailers, and heavy storage units. This high-security container padlock combines rugged build quality with a sleek profile designed to eliminate weak points.
What Is a Discus Padlock and Why Use One?
A discus padlock is a circular-style lock designed to reduce exposure to bolt cutters and pry tools. Its low profile and shielded shackle make it difficult to attack with common methods. That is why these locks are widely used in shipping, storage, and high-theft environments.
The Crab Lock takes the discus concept further by improving internal strength and weather resistance while maintaining a compact form that fits most standard container latches.
Why the Crab Lock Stands Out
This is not your average hardware store padlock. The Crab Discus Lock was developed with freight operators, yard managers, and logistics teams in mind.
Key features include:
-
Hardened stainless steel body that resists corrosion and impact
-
Shielded shackle that limits tool access and cutting angles
-
Smooth locking mechanism built to perform in dirt, salt, and moisture
-
Compact design that fits container doors, tool lockers, and trailer latches
Whether your container is traveling across the country or sitting overnight at a site, the Crab Lock helps eliminate security gaps.
Built for Container and Trailer Use
The Crab Lock is a perfect fit for:
-
Shipping containers in storage yards or in transit
-
Job site storage boxes and gates
-
Freight trailers and equipment haulers
-
Outdoor tool chests or mobile storage
Its durable body and secure fit make it ideal for rugged conditions where other locks struggle to perform.
How to Use the Crab Lock
The Crab Lock installs in seconds:
-
Insert the lock through your container latch or hasp
-
Rotate the key to engage the disc system
-
Confirm the lock clicks into place
-
Remove the key and tug to ensure a solid hold
Its round profile prevents common tools from finding grip points, adding another layer of defense.

Compact, tough, and engineered for high-risk environments, it is a trusted solution for serious operators.
