What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
Cut for the diatonic bass instrument's footprint. Chromatic and smaller-range instruments need their own adapter.
Detail 02
Sized for the largest, heaviest bar instrument in the range, so the mounting points sit wider than on alto or soprano adapters.
Detail 03
It only does its job on the matching trolley. On its own it holds nothing up.
Detail 04
This is stand hardware, not an instrument. Budget it alongside the trolley and the instrument itself.
