With more than 25 attachments - not recommended 29mm. Specially when the terminal up and should be dismantled. Legal stable design, My terminal can be opened without using force only to 29mm. But my tripod has a tube diameter of 32mm. Since Hilt only violence (cheeks "over it presses") or disassemble and then reassemble. Where the 40mm in the description here is I would like to know. I let them mounted on the tripod.
