This is our heavy duty cup holder holder mount designed to hold heavier control heads. The base expands out to 3.5". The mount is 9" in height, but can be adjusted using the swivel system.
The mount is built around Rams 1" ball system. So it will swivel into just about any position you need it to.
It comes with a 1/4 X 20 bolt that will thread directly into the Icom IC-705 or Icom IC-7100 control head.
