3-Rib 911C Hard Hat

Cap Style, ANSI Type I Class E and G, High Heat Exposure

The 3-Rib 911C is a cap style hard hat with a 6-point Flex-Gear® ratchet suspension, designed to protect the head from falling objects and bumps into stationary objects in high heat environments. The 911C includes a suspension which drops below the nape of the head, improving retention. Connect an optional chinstrap to ensure the hat remains on the head during a slip, trip, or fall event. Ideal for utilities, welding, foundries, and steel mills, where exposure to high temperatures can be present.
