The Sunbelt Manual Board Bin Mezzanine is a bin system designed for maximum storage capacity in a small area. Long length items such as lumber, pipe, and vinyl siding are hand loaded in pigeonhole type bins. The system can be configured with any number of openings, in any height, width or depth. The upper levels of a system can have addtional bins accessed via a front catwalk, or it can have a mezzanine floor for bulk or pallet storage. Each manual board bin is specifically engineered for a customer's unique requirements and loading conditions. Also see Sunbelt's automated Power Bin.
