I ordered the 3-6 foot closet Deluxe Configurations kit, and it was a breeze to install. I thought the sliding basket would be great under one of the shelves as a sock drawer! The spacing for the rails for the Configurations kit is 22 inches apart. Piece of cake. I had all brackets and shelves hung and then put together the basket. I went to attach the brackets into the rails, too wide. The basket is 23.5 inches wide. The brackets affix to the outside of the sliding frame. So the brackets end up not fitting into the vertical rails. I did make it fit, but the support brackets are held into the vertical rails but the inside "claw" of each support on the outside hole of the rail. The basket is great, but is not really "compatible" with the spacing of the closet kit. it is not possible to follow Rubbermaid's directions of spacing the rails 22 inches apart and make a 23.5 inch basket fit.
