Rotating Carousels eliminate the wasted time spent pacing back and forth in search of the binders you’re looking for. Binder carousels are available in two models: 31-1/2" and 36-1/2" diameter. Each tier of the Carousels hold 6-1/2 feet of binders (31-1/2" diameter, the 36-1/2" model provides even greater capacity), rotates independently of the others, and is accessible from all sides. Features sturdy construction with a steel center frame and laminated light gray finish. Add optional casters to make any floor unit mobile. Casters are not recommended for Carousels over 4-Tiers. Assembly required. Desktop unit is perfect for shared binders — stores up to 36 binders on your desk and comes complete with a worktop for added space. The 1-Tier model is only available in the smaller diameter.
