11' high - is it from the bottom of the mount? I am trying to understand if I will still have 360 degree rotation with WIse on my Gamma Progression X-ST without any additional modifications? Or maybe someone could tell the distance between the top of the mount and the top of diablo?
This distance:
Can’t see your picture but the Gamma X-ST is a lockout machine. Wise created a Gamma Adapter because the Wise was too low for Gamma Lockout Machines. The Gamma Adapter raises the Wise up 2” and prevents 360* rotation. If you don’t use the adapter and just mount the Wise on the tension bar you will be fine.
EDIT: You better use the Diablo though or you may break strings because the Wise sits low on a Gamma lockout. The Gamma lockout has to sit low to accommodate the string guide (aka string roller) which is on the lockout tensioner which is positioned just above and in front of the tensioner.
Different machine but pretty much the same:
