The music desk has a depth of 30 mm. The flexible clamp makes it easy to mount the holder in a wide variety of directions. The clamp can be attached to tables (0 to 48 mm thickness). The sturdy metal frame of the clamp is equipped with high-quality plastic inserts and the non-slip coating ensures that the clamp provides a secure and powerful hold. Thanks to the specially formed clamping surface, the clamp can be used on flat surfaces such as tables or shelfing, as well as on round tubing. The holder is collapsible for easy transport.
