Ercole MK-9 Mini Ball Head 25mm

Ercole M11-050A Umbrella Swivel Adapter with brass stud.

Due to its spring loaded clamping, this cold shoe clamp enables one to one-handedly mount shoe fitted equipment very easily. Its finger screw serves both as a push knob for opening the clamp and for tightening down the clamping securely.
It fits the standard shoe sizes of 18, 20 and 22mm.
The Cold Shoe Clamp is tapped with 1/4″-20 and 3/8″-16 holes on the back side

The small aluminium ball head features a universal female thread at the bottom, making it compatible with any support. Thanks to the universal ¼” on top, it can hold any camera up to 1 kg/2.2lbs. It is very compact and lightweight and also enables portrait mode shooting.
