The Spider Pro is equipped with two pairs of extendable and continuously height-adjustable support arms (the upper pair of support arms is inclined at 15°). It can be optionally upgraded with a third pair of support arms (item 18865 or 18866) for an additional keyboard. In addition, the Spider Pro has a 3/8" or 5/8" threaded connector at the top of the column for attaching a microphone arm. A reinforced inclination of the column allows for more comfortable playing and a better view of the lower keyboard. The foldable foot construction offers plenty of room for pedals and optimal legroom. The Spider Pro can be folded quickly and compactly. The optionally available bag (item 18851) provides protection and makes the stand easy to transport.
