The Lectrosonics SMBCDN Machined Wire Belt Clip is specially designed for single battery SM series transmitters. It helps to attach to the SM transmitter with a set screw and allowing the transmitter to be worn on a belt or other wardrobe item, where a low profile is required. The antenna and mic connector will face down. The detent can be used for setting the screw and the included hex wrench used to tighten the screw firmly. In newer SM transmitters, there are two detents in the housing that allow precision alignment of the SM belt clip. The stainless steel spring clip comes with a machined aluminum bracket.
