The K2 Series hard hats with ratchet adjustment have a versatile shell without a rain trough. These hats feature additional strength and rigidity that other lightweight hard hats can't compete with. The accessory slots, 4-point nylon web suspension with forehead comfort band and crown pad make this head protection a favorite. This hard hat is made from HDPE, is ANSI Type I, Class E compliant, and it is easily adjustable with a 4-point chin strap and 3-level height adjustment.
