Width on this rack is not fixed: a 9.5 inch extension rod slots into each end of the top rail, stretching the frame from 31 to 49.5 inches as a wardrobe fills up. Below it a second rail adjusts through three heights for shirts or long coats, and two bottom bars spaced 11.5 inches apart take suitcases or storage boxes. Load ratings are given per rail, 45 pounds on the main rod, 22 pounds on the middle rod and 11 pounds on each extension and bottom bar. The frame stands 68 inches tall on thickened powder-coated metal tube, and quick-release buttons let the tubes connect or come apart without tools. Four casters swivel through 360 degrees and roll quietly, so the whole 7 pound rack moves room to room while still loaded.
