The thumbscrew helps lock accessories and has holes for hex spanner for further tightening.
And the ball heads, which are 360-degree adjustable, come with a spiral pattern to increase friction and bear up to 3kg of load.
At the stainless steel rosette joint, there is a spring for easier angle adjustment.
An ergonomically designed anti-off thumb lever, with a built-in thrust ball bearing, feels smooth and comfortable and quickly locks arm and ball heads in a second.
This rosette arm is CNC machined for more robustness and durability and also equipped with pads on both accessory mounts to prevent scratches.
