Question: are rubbermaid and closetmaid interchangeable?
Answer: Closetmaid shelf supports and shelves will fit on the Rubbermaid or Elfa vertical hangers and vice versa. If money is not a concern then buy the Elfa, built like a tank will last forever and looks better than the others with the right accessories. Rubbermaid is the least sturdy of the three but does the job.
