About HART Stack System
Walmart house brand, made by Keter. TTI announced it was ending the HART business by the end of 2025 (ToolGuyd), and Walmart has been clearing HART stock through 2026; the Stack System pieces were still sold new at Walmart, by Walmart.com and by Keter, on October 2, 2026, so the line stays current until they are gone.

Source: amazon.com ↗, checked Sep 30, 2026. 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.
