Q: 2. Will the Impact 6 Extension arm work with a Manfrotto Super Clamp?

A: Absolutely. It's made to fit, quite sturdy too.

Q: 3. Can it securely attach to a 2x6 beam?

A: The Manfrotto 035RL Super Clamp with Standard Stud can attach to a 2x6 beam, but one should use a safety cable like the Impact Safety Cable (18"), B&H # IMSC1.518 (https://bhpho.to/3Yg3t0L).

Q: 6. Do I need a female 1/4 -20 to Male 3/8 adapter to connect this to a Manfrotto 175 spring clamp or 175F Justin clamp and the other end to a super clamp?

A: The non hex stud end will fit in a Justin clamp. But it is recommended to use a super clamp. The 5/8 hex stud end will secure much more and can handle more weight than a Justin clamp.

Q: 7. If this clamp's stud was oriented horizontally, parallel to a table top, could the 1/4-20 threaded end support 5-10 lbs. without it snapping off? If not, is there a stud that is made of steel that would be compatible?

A: The 1/4" thread would not be stable for an item that weighs 5-10 lbs. If you prefer to use a quick release plate, the Manfrotto 323 RC2 System Quick Release Adapter with 200PL-14 Plate, BH # MA323 screwed into the Manfrotto 037 Reversible Short Stud, with 3/8" & 1/4"-20 Threads (Brass), BH # MA037 would be better. The Short Stud should have its 3/8" thread facing towards the bottom of the quick release.

Q: 8. How hard is it to bend?

A: It is easy to bend

Q: 9. This evidently is not a true ratchet like a socket wrench ratchet. But does it have the ability to have the handle pulled out, re-positioned, and then back in to a tightening mode?

A: Unfortunately, this model lacks the ratchet handle function.

Q: 10. Could the super clamp and this arm fall off on a motorcycle at speed? I think the clamp would stay in place but the arm might bend. I will be using a GoPro (ie not heavy).

A: Get a Ram Mount. (company name). Ton of options for motorcycles.
