The Bullard USRX, a dual purpose Urban Search ' Rescue and Structural Firefighting helmet (compliant to both NFPA 1951-2001 ' NFPA 1971-2000), is designed to protect first responders in every USAR application, from high angle to confined space rescue. The outer shell of the USRX is made of the same high-heat Ultem thermoplastic, which, combined with other features, makes Bullard's structural fire helmets and thermal imagers Bullard Tough. The Bullard Sure-Lock ratchet headband offers both a quick-turn of the knob head size adjustment and a 3-position height adjuster for balance and comfort. The USRX comes standard with 3-point chin strap, ESS goggles and Bullard's Quick-Attach Blade mounting system.
