This Crown Verity ZCV-2090 red old style pilot knob replaces the one that comes standard with old model Crown Verity gas grills. The knob is used for operating the pilot light, and features an easy-to-grasp design for comfortable use. It ensures that the grill is operational at all times, preventing you from having to limit the menu due to inoperable equipment. This part is an old style knob, but works on all gas grills.
