Helm MC-1100 Standard Microphone Clip No more unsightly rust or scratches from microphone clips made of steel. Helm's attractive, one-piece microphone clip molded of salt-water safe nylon is 1 3/8" square. The clever design protects the finish of the fiberglass or teak surface where the microphone slides into the clip and features an integral spring pressure finger to hold the microphone in place. Fits all standard microphones on hailers, C.B.'s, and two-way radios. The Microphone Clip comes complete with two stainless screws for mounting. One complete unit per package.
