P1A Radius Roller for Cornets and Trumpets
The P1A is the answer for rolling out dents in the Bell stem area. Also you can get into areas you could not get to in the past with a roller. This very handy double handled tool comes with three different size radius rollers to cover most bell stem sections from front to back. It is possible to get closer and work around the valves & braces. The Hoop handle was designed to clear the valve section.
