Q: 1. How do you easily open & close the legs? Is there a trick I’m missing? I’m finding it very difficult to do without a 2nd person.

A: The Neewer Stainless Steel C-Stand with Casters and Boom Arm (10') can be a bit tricky but should not be too hard to open and close. Make sure the boom is straight up and not horizontal, which should help.

Q: 2. From Description: "Included is an adjustable 4.3 to 7.2' boom arm that can support up to 33 lb." Is this including the counterweight, or can it support a 33lb load on one end at max extension?

A: The load capacity at full extension on the Neewer Stainless Steel C-Stand with Casters and Boom Arm would include the counterweight.

Q: 6. Is this really a reducer bushing? The specs show OUTER (outside) thread is 3/8 and INNER (inside) thread is 1/4 . The photo shown doesn't show a reducing type. Thanks.

A: I think you already answered your own question, its a 3/8 male by quarter inch female bushing. If your tripod is quarter inch male thread you can screw the 3/8 ball head on the tripod

Q: 7. Does it include reel?

A: No, it does not include a reel I would highly recommend the Hewes stainless steel reels. They are more expensive, but most of the others on the market are only a half-step above junk.

Q: 8. OK: I think I have the answer to my question: This depends on how one is viewing the situation: this is a reducer if viewed from the object to be clamped, e.g., a camera clamp with originally 1/4 socket, and needs to be mounted to a tripod with 3/8 stud. I am looking for something that goes in the opposite direction: my tripod stud is 3/8 , and need to find a bushing that will reduce the TRIPOD 3/8 stud to 1/4 . The photo will be quite different for this type. Can the experts help, please??
