Twist Locks (Set of 4)

Twist Locks (Set of 4) for Sale

Stacking and securing shipping containers safely comes down to the connection points between them, and this set of four heavy-duty twist locks provides exactly that. Machined from heavy-duty steel and compatible with all standard ISO containers, these twist locks create a certified, positive link between stacked units, preventing dangerous movement during transport, storage, and lifting. They’re an essential accessory for anyone building a multi-container setup or hauling boxes by road, rail, or sea.

Secure Stacking You Can Trust

Each twist lock engages the corner castings of two containers with a quick-action locking mechanism that’s easy to set and release by hand. Once locked, the units are mechanically joined, so wind, transit vibration, and site activity won’t shift them out of alignment. The set of four locks the four corners of a container, and the system is rated for stacking containers up to four high, giving you the ability to build safely upward when ground space is tight.

Built for the Road, Rail, and Sea

Because these are the same style of fitting used across road, rail, and sea freight, they hold up to demanding real-world use. A corrosion-resistant finish protects against rust from rain and salt air, so they keep working season after season, whether the containers stay put on a yard or move regularly between sites. The result is a safer worksite and cargo that stays exactly where you put it.
