The extension plate is a great addtion to our very popular cup holder mount series.
The cup holder portion base expands out to 3 3/4" in diameter. When it is not expanded the base is 2 1/2" in diameter. The new HT holder has a padded surface to protect your device.
The extension bracket is made from lightweight strong aluminum. If you already have the cup holder portion you can purchase it separtely for $19.95. Click here to get one.
As long as your HT and your speaker microphone have either a belt clip or button mount this will work for you.
