Incorrect dimensions. My wall unit is 49 3/8 inches. Article says it is 47.25 inches. I had to place 1 of the 3 bars on each end and mount the middle one higher to accommodate the oversized bar. I didn't even put the caps on until I realized the frame didn't fit. Each rack is 17 inches long and measures 51 inches. With covers that would be 52.5 inches.
