Jansen small hardwood caster cups provide great protection for your
floor, carpet or rugs. The small hardwood caster cup fits many piano
caster sizes including typical single-wheel grand and upright piano caster styles.
These piano caster cups come in a variety of finishes including
Polished Ebony, Mahogany, Walnut, White, and Unfinished. Each piano
caster cup is sold separately, so don't forget to order 3 for a typical
grand set or 4 for your upright.
Outer diameter: 3½"
Inner diameter: 1¾"
The finish is a perfect match to my upright Yamaha Disklavier. Very solid and the right size for the smaller casters of an upright. The only negative is that it took two of us to lift the piano carefully and slide each caster in place. That piano was really heavy.
Do these caster cups have felt on the bottom? No, the cups are finely sanded on the bottom and the manufacturer recommends NOT using felt on the bottom.
How do I know these cups will fit my brand of piano? They are universal and should fit all pianos in the categories mentioned; however, measuring your casters is always a good idea.
Will these caster cups work for other furniture as well? Yes, they work well for any heavy furniture.
