Professional Hongtoo Gimbal Shock Absorption Arm Camera Video Stabilizer, Payload 5.5kg Approximately 30cm x 14cm, 990 grams. Mounting pole size is 32-36mm. I purchased this from overseas a few years ago for work, but the project was canceled and I never used it. I don't think I'll be using it in the future, so I'm putting it up for sale. There is no rust. If anyone needs it, please consider purchasing. I will wait patiently.
