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)
As I begin to produce a variety of rims, they will be available for this model.
