Honeywell Fibre-Metal FM70DCCL Cap Peak-Mounted Faceshield System features a lightweight, dielectric bracket which can be mounted on the front peak of the cap. This dual channel system uses one channel to anchor the bracket to the cap while the other channel is used to lock the work position of the window and pivot it up and out when not needed. Bracket is made from strong, heat-resistant Noryl and is perfect for extended outdoor use. It includes a 4″ deep chin guard and a 0.04″ propionate clear window for better viewing clarity. The locked channels create a positive seal to prevent the debris from filtering between the cap and Faceshield.
