This model is a medium large cup suitable for most situations on your large bore (symphony) tenor trombone.                                               The standard rim is medium wide in diameter, with a rounded inner profile. As this is a radius, you can’t specify the diameter as a specific dimension, here is a graphic.                                                                                  (click here to open a larger picture in a new tab)
