Vinten 3104-3 Adaptor 4-bolt Flat Base to 150mm Bowl

The 3104-3 converts a four-bolt flat base into a 150 mm levelling bowl. Vinten lists it for the robotic range, where an ICE, FH-155 or FHR-158 head has to land on a support that presents the flat four-hole pattern.

With the bowl in place the head levels through the clamp underneath rather than by adjusting the support, which matters on a robotic install that is set once and left. It bolts down with the standard four-hole hardware.
