The Hercules DS520B trombone stand is much adored by trombone players as they last a very long time.
The trombone rests on the braces of the handslide so there is no risk of damaging the bell while placing it or removing it from the stand. The width can easily be adjusted by a simple mechanism so it can fit many trombone models.
The tripod legs allow for a stable resting position as there is no room for the trombone to wobble. The legs can also be folded to transport around.
