This series from UNI-LOC consists of four compact ball and socket heads constructed with nylon cups to ensure a smooth ball motion. On the standard 25 ball head, a single lever locks both the ball and the revolving base. On the newer 25R Ball Head, an new design has been incorporated where the revolving base and the ball have independent, separate levers. Standard round platform and quick release versions are available for both types..

It may also be purchased separately as an attachment to fit other makes of monopods

The UNI-LOC 30 ball heads are made in a series of six heads, divided into two categories: three revolving base and three standard base. Each combines a patented internal locking mechanism, nylon cups for smooth ball motion and locking lever to give positive ball lock.

UNI-LOC 60 ball heads are designed for the larger camera formats, and uses a 60mm diameter ball which in turn runs in substantial nylon cups. Very positive locking is effected by a large round locking knob. A smaller seperate knob applies frictional adjustment to the ball. Two versions are available, one standard, and one with a revolving base. A new large easily located quick release camera plate for these heads are available now available.
