Lightweight, durable and highly portable, these music stands transform into a convenient, self-contained carrying case. The folding extensions provide four-sheet capacity, the desk angle is adjustable, and a patented locking system ensures maximum stability. The Petersen Music Stand has adjustable height (from 23″ to 50″), and can accommodate standard music stand lamps. Perfectly suited for musicians looking for the reliable functionality of a large metal stand, but the portability of a collapsible wire one.
