The Ludwig/Musser?P14471?3" Caster comes standard on Professional and Grand Symphonic timpani, as well as all models of chimes. This wheel is heavy-duty compared to the ones that come on Universal or Standard series timpani, complete with a locking mechanism.
This caster will fit on any Ludwig Timpani, but if you're planning on using them on anything but Professional or Grand Symphonic drums you will need two per timpano to keep it level.
