The John Boos R-Board 20 × 15-inch maple cutting board is a 1.5-inch thick reversible edge-grain block — Boos’s largest standard R-Board, sized for restaurant-style home kitchens.
John Boos has manufactured large-format maple cutting boards in Effingham, Illinois since 1887. The 20 × 15 size accommodates the prep volume that serious home cooks generate for holidays and entertaining.
Use the R-Board 20×15 for full-meal prep stations, entertaining, and as the centerpiece block of a butcher-block kitchen. The 12-lb weight resists movement during heavy chopping.
