Set of 3 Trombone Slide Removal Collars

The Trombone Slide Remover Collars are now made with two size openings. The G32A set is 15.2mm to fit regular trombones and the G32B is 16.7mm for bass trombones. Both sets consist of two tapered collars and one straight wedge collar. The two tapered collars are inserted in the crack between the threads and the nut on opposite sides of the frozen joint. When pressed toward each other they grow in thickness, forcing the bell section apart from the slide section. If there is too much space in the crack after the two tapered collars are inserted, the straight wedge can be inserted as a shim. Press together by hand, by tapping gently with a rawhide mallet or by gently pressing in a vise.
