Lowe's house brand. Lowe's cleared the original CaseStack boxes in spring 2026; a second generation, said to stack with the first, was announced for 2026 but still had no product pages on October 2, 2026 (only side-rail and mounting-plate accessories). Clearance is not discontinuation: the original boxes are still listed as current until Lowe's or Kobalt says otherwise.
