The Jackson Safety hard hat interchange system is a must-have accessory when workers need to wear a hard hat with a face shield or welding helmet while on the job. The smart design lets you quickly attach or detach a face shield or welding helmet from the hard without removing it, so you stay protected at all times. The system makes an audible "click" so you'll know the equipment is assembled correctly. It features a vertical lock-in to eliminate helmet and face shield creep and is built with a push button quick release which works even while wearing gloves.
