My wire racks are maybe 20 years old. They actually do not make 'em like that anymore. Newer ones are much thinner and the corners don't fit mine by a mile. Or 1.61 Km. Take a very close look at the design, and you'll see the subtle differences. I have a significant number of the old wire cubes, so this entire box will see use. Already coming together like a dream! Pictured is one of my originals (right) and the tiny new ones.
