Works great if you build your entire closet system around it.
The basket is 23.5" wide. That means it fits between two uprights that are 24" apart. Unfortunately nothing else that Rubbermaid sells is this width. Whether you use the "Classic Closet Kit", the "Deluxe Closet Kit", or the "homefree SERIES Adjustable Closet System"; all rails are set at 22" inches apart.
Luckily I bought these first and then setup the rest of the closet around them.

Good Luck everyone!
