Features: Wooden Resting Base: This set of 4 piano caster cups uses a polished body to give upright piano and rounded heavy legs a stable resting point during daily use. Recessed Cup Design: The curved inner bowl helps seat each wheel or rounded leg in place, creating a centered hold that supports secure positioning on home floors. Floor Buffer Layer: A black bottom pad creates a gentle layer between heavy pressure points and the floor, helping reduce direct marks and visible floor scuffs. Fit Check Guidance: Each cup measures 9cm/3.54inch outer diameter with 6cm/2.36inch inner diameter, giving you clear reference points before placing or rounded feet. Home Use Coverage: Built for upright pianos and other heavy legs, these cups help guard hardwood and similar indoor floors where stable wheel support matters.
