Mounts to most hard hats without an adaptor and easily swing out of the way when not in use.
∙ Lightweight, durable plastic construction is non-conductive and dielectric for tough environments.
∙ An "at-rest" position eliminates contact with other gear to reduce contamination and distortion.
∙ Works with most slotted hardhats
