Related Questions and Answers

Q: 1. Can the Avenger A4039CS stand attach any caster wheels?

A: Yes Greg it does!

Q: 2. What is the best way to include a counterweight sandbag or other weight when using the stand in boom mode? Are people putting a sand bag somehow on the opposite end of the boom arm? Or something else?

A: It comes with a very nicely made canvas bag that you can fill with sand and hang from the hook that's at the end of boom. This is a fantastic boom stand...well worth the money.

Q: 3. The maximum extension is 105 (according to a Q&A response)--but don't you have to back it down about 18 to 24 for a counterbalance? I only need to put about 7 or 8 pounds on the end. Can it hold that without a counterbalance at full extension? How much weight can it take at full extension without a counterbalance?

A: The maximum extension is 105 with the pushed forward completely and the top riser extended on it. You would only need about 18 at the end to clamp on a counterweight, which should be used even if the light being placed on it is only 8 lbs for safety.

Q: 4. What is the load rating of this stand?

A: Your answer is found in the specs section of this listing - 26.46 lb (12 kg)

Q: 5. Does anyone out there have more details about the specs of the boom arm, and boom function of this stand? There is not much on B&H here, or the Avenger manufacturer site. Anyone have photos of the boom extended? Experiences with various lights and modifiers on the boom arm of this stand? Also: anyone have first hand experience with both this stand and the Avenger A4041B boom stand? How do these stands compare outside what I can compare on the spec sheets. Thanks for your help!

A: These are both very good boom/stand combo kits.The Avenger A40441B, a href= http://bhpho.to/Nfg4vn target= _blank http://bhpho.to/Nfg4vn/a is a bit stronger and taller. The specifications listed under that tab for both are really all boom equipment have. The A40441B can support at the most 33lbs not extended and fully extended up to 22 lbs.The A4039CS can support up to 26 lbs at most extensions and it is smoother to use and in chrome is visually niceUsing both they really are similar. The A40441B does come with a counter weight which you should use. And the A4039CS does not so that is an added item to get.

Q: 9. Does anyone know the maximum load for the boom arm at minimum extension?
