The table features a Thoracic Air-Breakaway Section controlled by a foot pedal. The pedal increases or decreases the air-spring pressure in the thoracic and lumbar sections providing a controlled recoil action. It can also be locked in any position down to 51/2” for treating patients with a large abdominal region. The drops included on the Air-Drop HA90C are Cervical, Thoracic, Lumbar, and Pelvic. The Cervical Drop has dual action enabling either straight or forward-drop action. All drops are controlled by the included foot-strips located on both sides of the table. Like all Hill Adjustables, the Air-Drop HA90C has electric adjustable-height. Height is adjusted with a rocker foot pedal that is mounted to the base and can be accessed from either side of the table. An operating range from 23 1/2” to 33” or 21 1/2″ to 31″ allows the doctor to work at a comfortable treatment level.
