Large shank
Check this shank designation when selecting the 00AL.

Independent shopping perspective
The gold 00AL is the large-shank Heritage Series option identified for contrabass trombone. Its 28mm cup, 6.40mm rim, 8.15mm throat, and open backbore define this particular model. It is voiced as dark and round, with projection and clarity. Heritage construction concentrates mass near the throat and backbore while using thinner upper walls, a combination designed for sensitivity at softer dynamics, easier upper-register articulation, and power across changing dynamic levels.
