Attach accessories to Mitchell mounting plates with this Mitchell Threaded Collar & Castle Nut from Kupo. This set features a CNC-machined aluminum mounting collar and a yellow zinc-plated steel castle nut that enables mounting cheese plates, accessories, and other grip gear on a Mitchell mounting plate, which is common to the cinema industry. The castle nut features standard threading, a smooth round circumference, and raised studs that allow you to grip and tighten or loosen the nut as needed and give the castle nut its name.

The collar is machined with threads that match a standard Mitchell castle nut (not included) making it compatible with a variety of tripod supports and risers. A pair of M7 and M10 countersunk through-holes enables you to mount the collar to supports. Likewise, a pair of threaded 1/4"-20 and 3/8"-16 threaded holes with 1" on-center spacing is suitable for attaching standard cheese plates to the collar. Additionally, the interior of the collar is threaded, allowing it to accept optional accessories from Kupo, such as the Mitchell thread collar to Baby pin stud adapter.

A: Your Elinchrom Head should fit on the 6-inch pin on the smaller, grooved, off-set end of the pin. But, first slide the small end of the pin through the appropriate-sized hole in the grip-head (on the arm extension) after turning the handle on the grip head to loosen the grip head and open the holes wide enough to slip the pin through. Then tighten the grip head handle to hold the pin in place, and to the angle you choose. Once that is done, you can then attach the Elinchrom head to the grooved end of the pin and re-adjust the angle and height.

The collar at the end of the pin acts as an anchor to prevent the pin from sliding completely through a grip clamp.

A: This pin is not threaded at all. It's designed to be used in a pinch-clamp of a C-stand. The end with the reduced diameter is where a strobe would be added, and tightened into place by the set screw of the strobe.
