Our F500 Series ratcheting headgear offers an extra margin of protection when severe working conditions require it. Features a Speedy Loop mounting system that offers on/off welding helmet or faceshield mounting on protective caps. This headgear also resists heat and features a slot/pin mechanism with locking cams. 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 can be attached to cap style hard hats.
