These collapsible steel and aluminum stands handle large booms or arrays easily and can get your mics into all the best-sounding locations. These stands are rated for a 66 lb. load capacity. Articulated legs (the 13 has one, but the 24 has 3) keep stands vertical on stairs, slopes or uneven floors. These stands are recommended if you need to boom out a significant amount of weight. There are vertical extensions available which provide additional height, but also limit the load capacity to 22 lbs. 5/8"-27 mic threads are standard, European 3/8" or Japanese 1/2" are optional.
