The 3/8" Boom Adaptor Swivel from Rycote allows devices such as portable audio recorders and cameras with female 1/4" threading to mount on a 3/8" male thread commonly found on mic stands and boom poles. It can also be attached to a camera hot shoe with included adapter.

The boom adapter is black and made of plastic and brass components. It features a 180° swivel allowing attached devices to be positioned on multiple angles and the integrated cable clamp helps reduce or eliminate extraneous noise caused by loose cabling.
