The Adaptor Swivel has been designed to allow products with a female 1/4" thread (ie a portable audio recorder or camera) to be mounted on a 3/8" male thread, mic stand or boom pole, or a camera hot shoe. The adaptor is made of plastic and brass components.  It features a 180° swivel for improved ease-of-use, as well as an integrated cable clamp designed to greatly reduce cable-borne noise.
