The 5G Above Desk mechanism has a 13.5” height adjustment range – 7.5” above track to 6” below track. Comes with synthetic foam wrist rest and standard 27” track.
The height range adjustment is 5” from where it is mounted under the desk. The height adjustment above the desk surface depends on thickness of desk surface. If you have a 3” thick work surface, it will only raise about 2” above the desk. If you have a 1” thick work surface, it will raise 4” above the desk.
