Related Questions and Answers

Q: 1. I'm finding that this item will not work with the Manfrotto super clamp I have or the 9.Solutions type super clamps. In the case of the Manfrotto, it does not appear to go in far enough. In the case of the 9.Solutions clamp, it will not go in at all. I'm having similar problems with the same type of arm made by Manfrotto. In all cases, a standard 6 sided 5/8" spigot will easily fit in all of the clamps. Is anyone else having this problem?

A: This is the 1st I have heard the issue. I would recommend calling into B&H for troubleshooting, connecting with a B&H live chat agent, or visiting the superstore.

Q: 2. Can the cold shoe attachment be replaced by a 1/4 20 male thread?
