The Systainer originated from the need to transport materials and tools so they were well organized and easy to move. This was accomplished through a unique patented case system, which enables all Systainers to be stacked and linked together.

The "LOC" in T-LOC stands for: Lock, Open and Connect! The T-LOC system sets the new benchmark in innovation, design and functionality. The central element is the T-LOC catch, which enables one-handed locking, opening and connecting. The T-LOC catch offers fast linking of individual units so they can all be carried as a single unit.

To stack the T-LOC Systainers, simply click into the snap-in position at the back, turn the T-LOC catch and that's it! A unique feature is that you have access to the contents of a T-LOC Systainer halfway down the stack of Systainers, without releasing the link, by simply rotating the T-LOC counterclockwise 90 degrees from the locked position.

Tanos uses 100% ABS polymer, combined with the most stable design structure, for maximum durability. All T-LOC Systainers are sturdy and impact resistant, as well as dust proof. Every component of the T-LOC such as the body, lid, handle or catch can be replaced easily, which guarantees long life.
