I need a 4 space rack that has a total depth with the lids off to be no more than 12 inches. I can't really tell from most of the descriptions. They say they're 10.25" one way and 14.25" another way and I don't know what the heck they mean. I have between 10" and 12" to work with on top of my combo. With the lids off, the total box can't have a longer depth than 12". Anyone know which shallow racks qualify?
