This adapter allows one to use the industry-standard boom stand that accepts standard Bausch & Lomb pin-type accessories (focus drives, etc) with focus drives that use a 25mm diameter post. The post has a knuckle joint that allows the inclination to be adjusted through an angle of greater than 120 degrees. Overall length of the post is approximately 150mm. There is supposed to be a keeper nut on the end of the post however it is not present.

These posts are in excellent condition and very nicely made.
