Features: Grand Piano Support: These caster cups sit under grand piano to help separate the wheel point from hard floors while keeping the copy centered on shared everyday placement needs. Recessed Structure: Each cup combines a body with a rounded recessed seat that helps hold the wheel position more neatly during home setup, studio placement, or room changes. Fit Check Guidance: The shared size profile includes about 12.5cm/4.92inch outer diameter, 9.6cm/3.78inch inner diameter, and 2.5cm/0.98inch height for placement review. Set Of Three Pieces: This set of 3 supports the common three point layout used under grand piano caster giving a coordinated setup for music rooms, practice corners, or teaching areas. Cleaner Floor Buffer: The cup shape helps reduce direct wheel pressure on hard floors and helps spread the touch point load in a conservative way for routine home or studio piano placement.
