When you need to hold a desk in a stable horizontal position, the Table-Lock is the answer. The Manhasset Table-Lock is ideal for converting Manhasset music stands for use with synthetic drum pads, keyboards, or other applications requiring a flat platform. In moments, this accessory can be fitted on all standard necked Manhasset music stands (all except the voyager portable stands). With only two screws, your stand is converted to a table platform that is locked in the horizontal position.
