The manufacturer doesn't specify the exact weight capacity of the Stanley STST14021 Tool Organizer.

But I can share a bit about its design that might help. It's made from sturdy plastic, which suggests it should handle regular use without any issues. While we don't have an exact number for its weight capacity, it seems suited for typical tool storage and transport needs.

According to our research, people find it lightweight and easy to carry, even without a handle on the lid, thanks to comfortable side handles. Plus, the slim shape makes it easy to fit into backpacks or tool bags.

The clear lid is also handy since you can see what's inside without needing to open it.

So if you're looking for a practical tool organizer for everyday tasks, this one could work well for you, even without knowing the exact weight capacity.
