The Jackson Safety CH-400V Industrial Climbing Vented Hard Hat features a “climbing inspired” hard hat shape. The 6-pt ratcheting suspension fits head sizes 6-1/2 to 8 making it more comfortable than “traditional” hard hats. Specially designed sliding vent holes allow easy opening and closing depending on weather conditions. Lightweight in design, molded from high-quality ABS materials, this hard hat is ideal for at-height and scaffolding work, confined space applications, construction sites requiring chin straps and general all-around head protection. CH-400V hard hat meets ANSI Z89.1, Type 1, and Class C. Choose from a variety of colors: white, yellow, orange, high-visibility yellow green, and black.
