Impact Extension Arm Reviews
Exactly what was needed.

This is a quality product. One drawback is the Impact Super Clamp connection socket is set up for the clamp to be on a pole to have the extension arm to be at a 90 degree angle to the clamp. If you connect the super clamp to a table the extension arm is at a 45 degree angle.
Solid & Dependable!

This is my 3rd time purchasing the 6 extension arm. One is holding a Sony EV10ii. Another is holding an Obsbot Me. ZERO complaints.

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?
Hello James, I use these with Matthews Mafer Clamps without issue. Respectfully, Joseph from the U.S.A.

Is there a baby pin spigot that fits well?
Is there a baby pin spigot that fits well?
Aside from the included spigot, the Impact SRP-113 Long Double Stud 5/8", BH # IMSRP113 can also fit well.
