Skyscraper Style
The Skyscraper Palm Key Riser brings the palm keys 14mm (.55 in) closer to the hand, extending twice as much as the original palm key riser. The new ergonomic reach increases speed and ease of playing. Many people find the ideal combination is two skyscraper palm key risers on the high D and F keys, and one original palm key riser for the high Eb key.
