The clamp has moderate tightness and can be opened to a width of about 0.31 inches or 8 mm, which will not harm the instrument.
The tightness of the clamp is related to the thickness of the music stand.
If your instrument is thin and you want your music score to be clamped tighter, adding a paper shell of appropriate thickness to the clamping position will have the perfect effect.
The material is metal plating, the appearance is bright, beautiful and practical, but it is very strong and has a long service life.
Exquisite workmanship, compact and lightweight, easy to carry, convenient and practical.
