[CAUT] harpsichord stand casters?

[John Minor]

Our harpsichord prof has seen casters on harpsichord stands that seem to work well, and I have been asked to install some on our instruments. She has seen them on instruments at Temple University, North Texas State, and La Fayette College. Anyone seen these instruments, or know what type of casters work well?

Thanks for any help.
