Rev-A-Shelf's Two-Tier baskets make other 2-shelf units fail in comparison. With the heavy gage construction, ball-bearing Soft Close slides on both baskets, and multiple mounting points, this is the best two-tier unit on the market. With heavy duty slides on each basket you don't have to worry about overloading or bending the wire as these units will work in almost any size base cabinet. The multiple mounting points make sure that any sort of side to side movement is limited. Finish the look off by adding the optional door mount kit.
