This stand includes nearly everything you need for starting a studio project. At its core is a telescoping vertical shaft and an extra long telescoping boom with a solid steel counterweight. The 40-teeth boom clutch means non-slip locking power. Added to the end of the boom are a Posi-Lok mini-boom arm and a MY100 mic clip. The four folding legs that lock in place and attached locking casters make for a remarkably stable foundation. And, this studio boom can be taken anywhere as the entire stand folds for travel.
