The Prince Castle MHB100MB-NA is the foundation of the Modular Holding Bin system. Every MHB configuration starts with one Main Base, which provides power distribution and connectivity for the holding modules stacked above it. The Main Base includes a top cover and connects to a standard 120V/NEMA 5-15P outlet.

Stack holding modules (MHB100HM1 or MHB100HM1-SS) directly onto the Main Base. To expand horizontally, add Expansion Bases (MHB100EB) alongside the Main Base — up to 8 total modules can run on a single circuit, maximizing power efficiency while minimizing electrical demands.

The compact 10.28" × 13.76" footprint means the MHB system fits in spaces where traditional holding bins cannot, making it ideal for operations with limited counter space that still need flexible, scalable holding capacity.
