# What stacks with HART Stack System?

> HART Stack System stacks directly with Keter Stack-N-Roll. Each pair below names its source.

- **Keter Stack-N-Roll** — locks on directly. Confidence: inferred. [Source](https://www.amazon.com/Keter-250927-Stack-Storage-System/dp/B09RGLRC7F), checked 2026-09-30. Same maker, same part number: Amazon lists the HART Stack System under Keter's model number 250927, the number Keter gives its own Stack & Roll system (keter.com/en-gb, 250927), and Keter makes HART's plastic storage (ToolGuyd, 2022). Neither brand says in so many words that the two lock together.
