Honeywell Fibre-Metal Noryl F5400 Headgear with 5000 Speedy Loop mounting features a 4″ crown and is designed to use with protective cups. The ratchet headband extends the security without increasing weight and suits easily on the required spectacles or respirators. Headgear integrates a wide vision 8″ X 17″ windows and screens that offers 40% more protective area. The channel grip system mounts windows and grips them in place in a deep recessed channel to secure from dirt and debris. The free floating headgear promotes more permanent mounting for longer term or high activity applications and it can be attached to E2Q or P2NQP2HNQ series hard hats.
