High pressure laminate on 1 1/8" solid core high-performance particleboard provides extreme durability. Panel attachment brackets (incl.) allow any worksurface height to be 26 1/2", 27 3/4", or 29 1/2" to ensure a comfortable working environment. Grommets help prevent tripping over loose wires and cables by routing under worksurface. Smooth, radius edges offer clean, flowing lines for a professional appearance.
