This includes the two main parts of the adjustable arm, thumbscrew, plastic washer, and rubber washer for the Umbra Tall support.
This arm is the only difference between The Umbra Tall and the Umbra Standard or Umbra Short. If you have a Standard or Short, you can purchase this arm to convert it to a Tall.
The assembly is the same high quality as the rest of the Umbra model and extends the arm exactly as I had hoped. Thank you.
Easy to switch out, just what I needed.
