5521 Rosette Arm Support 11"（BumbleBee Edition）

The thumbscrew helps lock accessories and has holes for a hex spanner for further tightening.  

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 is also equipped with pads on both accessory mounts to prevent scratches.
