Description

The Hadley H00640Z is a cab dual air horn designed for use on concrete mixer trucks. It delivers a powerful hi-lo tone that is audible over construction site noise, making it effective for driver alerts during loading, maneuvering, and road operations. This air horn connects to the truck's air brake system via a 1/4-inch NPT inlet and produces 133 dB of sound.
