Q: 2. Is additional screw needed to mount to film CB-32?

A: In my FLM ball head, I turned the round plate and replaced it with the SRB-60 Quick Release Clamp using the screw that was attached to the FLM ball head. I only strengthened with the thread glue the connection of the screw with the ball head and screws with the SRB plate

Q: 3. I was wondering if there are any issues with this plate twisting while on camera, since it is a universal plate?

A: The QRP plates are the most solid I've ever used, even with minimal tightening. This is partially due to the rubber-and-cork pads.

Q: 6. Can the locking pin be removed?

Q: 7. Will this just screw right on my FLM CB24?

A: No. the thread on your CG24 is 1/4"/20. The thread on the SRB40 is 3/8"/16 . But you can make it fit easily by using an adapter bushing. A good one would be B&H # WIBS100.

A: Hi, the safety pin is not removable--it is spring-loaded and will retract into the body of the clamp if not in use.
