my closet is a fairly typical reach-in: almost 7' wide x 2' deep. The door opening is a typical 5', with sliding mirror doors.

IF YOU'RE CLOSET SOUNDS SIMILAR, DO NOT BUY THIS ADD-ON!!!

If you use this closet system, you know the uprights are 22" apart. In a 7' closet, that amounts to 3 "sections" (i.e., you could fit 3 of these basket drawers across, if you wanted to). Actually, you CAN'T, and here's why:

You can't put them in the middle, because the sliding mirror doors cover the middle!

Here's the kicker... You can't put them of the left or right, because at 18" deep, you can get it only 6" open before it bonks the door frame!

Again, do not buy if you're closet is less than 36" deep
