The microSpud is a 15mm to 1/4" 20 thread adapter and works in conjunction with similar kit like the Redrock microMount or the Zacuto Zicro mounts. When used together these allows just about any item to be connected to 15mm rods. We have threaded inserts to allow the microSpud to screw into larger diameter holes too.
The underside of the microSpud has a 1/4" threaded hole and can be used in conjunction with a hot shoe mount or other threaded accessory mount.
Combine with our Zacuto Z-american arms for an ideal way to the arm onto 15mm rods or use several with 15mm cage bar to mount a monitor and follow focus together for a focus puller system.
