I installed the T1 mic stand bracket on my mic stand last night. I was almost stumped. My mic stand is a Hercules brand and is wider than any of the cut-out templates in the documentation. I was all ready to post for help when I thought of just taking the insert out all together. That fit perfectly.
I may have missed it, but I'd suggest changing the template doucment to include a cut out for the thicker stands with instructions to remove the inserts.
