This includes the two main parts of the adjustable arm, thumbscrew, plastic washer, and rubber washer for the Atlas Short support.
This arm is the only difference between the Atlas Short and the Atlas Standard or Atlas Tall. If you have a Standard or Tall, you can purchase this arm to convert it to a Short.
Converted the standard one, which I originally plan to use only for classical, to the short model, so I can use it on all my acoustic guitars!
No more leg crossing!
It even reminds me not to cross my legs
