The On-Stage SM7122 is the American classic design that every band student has had for years. It has a two-section shaft with cam locking clutch, and folds for easy storage and portability with a spring-loaded trigger release. The two-section vertical shaft with cam locking clutch and tilting book plate features make this stand adjustable for sitting or standing positions. The fold-out extensions with a six-point hinge system can hold three 8.5" x 11" sheets.
