Title: Upgrade a Manhasset music stand
Review: I use a Shaft Lock because the rattle of an older Manhasset stand irritates me. Without the Shaft Lock the stand rattles every time I touch it and the sound is a distraction, especially when making a recording. If a music stand won't stay at the height one selects this Shaft Lock keeps it in place at any point one chooses. I bought these for two musician friends and am sure that it will increase the pleasure and convenience of their performing.
