It seems we never have enough cabinet space to store everything we have, and where we end up storing things isn't always where we need them. But, with the addition of Rev-A-Shelf's innovative 448 Sidekick, that's a problem of the past The design allows the unit to attach to any of the 448-BCSC series with Blum soft-close, and slides independently, providing access to both the "sidekick" and the main organizer to which it is attached. It creates one cohesive multipurpose storage solution, constructed from the same wood and chrome materials as Rev-A-Shelf's 448 pull outs.
