Q: 1. how do you use it?? I just bought it. There are no directions!

A: The user manual to the arm can be found here: https://bhpho.to/2KjwXWF

Q: 2. 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: 3. What is the maximum weight capacity?

A: Not specified but most superclamps have 15kg load limit.

Q: 4. I want to use with a LED monitor that weighs in at 1lb 7 ounces and a super clamp attached to video tripod leg. I don't like the hot shoe mount that came with the Elvid Fieldvision monitor. Do you think this would work?

A: That will be a little heavy for this, unless you plan to have it point straight down. I don't think it will maintain it's position with that much weight on it.

Q: 5. Is this compatible with the Manfrotto super clamp?

A: Yes, this arm is compatible with a Manfrotto Super Clamp.

Q: 6. Will this REALLY hold 8 lbs. if it extended out perfectly horizontally and the 8 lbs. is on the end?

A: Yes, the load capacity is based on the full extension of the arm, so it will hold up to 8 lbs.

Q: 7. Can the ball pins be rotated to various positions? If so, can they be locked in those positions?

A: Yes it does rotate

Q: 8. Are these good for keyboard trays for on-set monitor set-ups?

A: No, the Kupo 6" Extension Arm with Universal Adapter Spigot is not ideal for a keyboard tray due to the length of the extension.

Q: 9. Is there a baby pin spigot that fits well?

A: Aside from the included spigot, the Impact SRP-113 Long Double Stud 5/8", BH # IMSRP113 can also fit well. https://bhpho.to/3u0qoyz

Q: 10. What is the reasoning behind using different metal on the fixture ends? The Impact BHE-108 Is brass and the Impact BHE-108S Is steel. I would assume that steel is the strongest and most durable material, so why use brass - is it just a personal choice of aesthetics - where is there a more sound reason?

A: Brass is less likely to bind and would be easier to take apart. But yes steel would be a bit stronger.
