Clamp can be easily removed and fits many brands of ball heads & Gimbals including Arca-swiss, Jobu, RRS etc.
Use included Metric 6 flat head screw to mount onto a ballhead. Can be mounted onto 3/8" threaded post.
SUNWAYFOTO makes the ballhead balls from ellipsoidal form into more closer to spherical form.  At present, all of the better
makes of heads are ellipsoidal designed to produce progressive resistance to reduce accidents. In most cases  the  Y-axis diameter of the ball is about 0.07mm longer than the X-axis.      
SUNWAYFOTO only makes the ball Y-axis diameter only 0.03mm longer than the X-axis. The progessive resistance is still  present , but now the operation is silky smooth.        
DB-42DDH has two drop notch design. One for portrait, one for tilting. We have strengthened the shell through rigorous testing.       
Control knobs are 100% metal with no plastic or rubber, To ensure the operational smoothness, and also enhance the reliability and durability.
