Q: 1. I Cannot find manual describing how to open each leg and where they should positioned. I always unscrew the back of each leg, position about 60 degrees then re-tighten the back, is this right? I do not think so.

Q: 6. What is the 40 about? I want to make sure it can fit on my Tenba bag as my current impact one is too long after removing the legs.Tenba T488 TriPak

A: The minimum length (height) of this c-stand is 54 , and the legs are not removable, making it wider than your bag will allow. The main center section is close to 40 perhaps that is what they are referring to, but its overall length would be 54 and it's width, due to the legs would be 21 . You won't lug this around in a bag. I had hoped I could too, but after having it, considering its incredibly heavy duty build quality, I really don't mind carrying it separate. In fact, I lay it along the top outside of my bag and then lift the bag and the c-stand up by the bag handles. It works out just fine.

Q: 7. Can the slider leg move enough to straddle a flight of one or two steps?

Q: 9. I use and 3228w bogan manfritto tripod, is this compatible with this tripod?Thanks

A: The side arm extension fits on my Bogan tripod. At first I thought it would be a problem because there is a large hole for an oversized stud to mount on the tripod. The center mount is adaptable to large or small studs. You can mount it on almost any tripod. The same is true on the extended arms. A small or large stud comes with the unit to again mount almost anything on the arms. What does not come with the unit is a counterweight to go on the opposite arm. You can move the counterweight anywhere on the arm to help keep the center of gravity centered at the top of the tripod.

Q: 10. What do I need to attach a monolight to the grip head? Some sort of pin?

A: If you are trying to attach the monolight to the griphead at the end of the extension arm yes you need a pin. I just use a 5/8 x6 bolt from the hardware store. The extension are itself is 5/8 I believe so the monolight can be directly mounted to that end. Remember this is not a boom arm and you will need sandbags or other weight to help balance the weight you are hanging off the extension arm.
