The ideal extension to the Omega 18810 keyboard table for a second keyboard or a laptop. The large lower extension arms can even support the largest master keyboards. The upper extension arms can now also be adjusted down by 4 positions providing an unobstructed view of the lower keyboard. The height of the stacker can be adjusted as desired quickly and easily using a ratchet-lock. Thanks to a choice of 10 different heights, everyone will find their personal setting. In addition, the upper extension arms can be adjusted over 5 steps from 0° (horizontal) to 20° for further optimization of playing position. Self-adhesive rubber pads prevent scratches or slipping of instruments.
