Jansen Large Piano Caster Cups for Dual Wheel Piano Casters – 6.5" Diameter - Satin Black is backordered and will ship as soon as it is back in stock.
These American-made Jansen large piano caster cups are designed for pianos with dual wheel casters that need more room than a standard caster cup. With a 6.5" outer diameter and a 4.25" inner diameter, this is a very large, hard-to-find caster cup size that offers a broad footprint while still looking more proportionate than an oversized 7.5" cup under many grand pianos.
If your piano has large dual wheel casters and smaller caster cups are not wide enough, this size can be an excellent solution. These cups are made by Jansen in the USA from quality maple hardwood and are built to help protect hardwood, tile, low-pile carpet, and other flooring surfaces from caster wear and movement.

Who These 6.5" Caster Cups Are Best For
These are not common, small piano caster cups. This 6.5" model is a specialized option for customers who need a larger-than-standard cup for a piano with dual wheel casters. They are ideal when standard sizes look too small or do not provide enough room for the caster assembly, but you do not need the full oversized footprint of the 7.5" version.
For many customers, this size is the right middle ground: very large, but not the largest option available. They are especially useful for larger grand pianos, decorative dual brass wheel casters, and situations where appearance and fit both matter.
How to Measure
Before ordering, measure the full area of the caster that will sit inside the recessed bowl of the cup. The inner diameter is 4.25", so your caster needs to fit comfortably within that measurement. You will want at least a 1/4" of space in the bowl, so these caster cups will work with wheels that have a diameter of 4" or smaller.
Need an Even Larger Caster Cup?
If your piano has exceptionally large dual wheel casters, or if you want the widest and most oversized footprint possible, we also offer our 7.5" Extra Large Piano Caster Cups for Dual Wheel Casters.
You may want the larger 7.5" version if:
- Your caster assembly is too large to fit comfortably inside a 4.25" inner diameter--the 7.5" caster cups have an inner diameter of 5.5".
- You want more clearance around the wheel
- You prefer the visual look of a wider cup under a very large grand piano
- You want the largest piano caster cup size we offer to help disperse the weight of a heavy grand piano.

Frequently Asked Questions
How do I determine the right size caster cup for my piano?
How do I determine the right size caster cup for my piano?
- Piano caster cups have two measurements—an overall outer diameter and an inner diameter (bowl area). You need to make sure your piano wheel’s diameter and depth measurements fit within the inner diameter of the cup.
- In general, some space is needed between the wheel and walls of the cup. As the inside of caster cups are often tapered, an exact fit will not match—and would make for difficult installation. We recommend at least a quarter inch difference between the diameter of the inner caster cups and your wheels. For example, if your piano caster's are 2" wide, you need a caster cup that has an inner-diameter of at least 2.25".
