The unique design of the NS-HMC7 multi-angle helmet mount fits within a hard hat accessory slot and also attaches directly to the brim of most hard hats and fire helmets. Utilizing a one-hand operational tightening screw, this multi-purpose mount is compatible on either size of a traditional upward or downward size helmet or fire helmet. Enjoy both a forward and backward tilt as well the side-to-side tilt functionality. Choose between an above or below brim configuration and then tighten only once for a firm consistent hold. Mount meets the requirement of NFPA-1971-8.6 (2013).
