This cup holder mount truly requires no holes to drilled at all. The threaded stud mount on the face of this mount will screw into the Icom MB-63 mobile mounting bracket for the IC-706, It will screw into the MB-105 plate If you have an IC-7000, and if you have an IC-2820 it will screw into the metal mounting plate that came with your IC-2820. Please note the MB-63, MB-105 or IC-2820H metal mounting plate does not come with this mount. If you do not have this you can get them from your Icom Dealer or from Icom direct. We also have a side grip holder that will work if you do not wish to purchase the MB-63, MB-105, but this really is the best mounting solution for your control head.
The Cup Holder portion base expands out by turning the large knob at the base of the flexible shaft. This allows for a very snug fit into just about any cup holder
