(888) 312-8812 Login SignupThe PAI Rectangular Bell Air Horn is a single, 26-inch air horn designed to deliver a deep, commanding tone on heavy-duty trucks equipped with compressed-air systems. Its classic rectangular bell profile combines with a 7/16-24 straight female port to match common air-line connections on Mack and similar vehicles’ horn systems. Because this part is sold as the horn alone—not a full kit with valves or mounting hardware—it’s the correct choice when you’re replacing just the horn element rather than the entire assembly. The chrome-plated steel construction offers a tough, attention-getting appearance on the vehicle’s exterior while producing the authoritative sound expected from a truck horn. The PAI EM44930 air horn stands out as a proper direct replacement when the horn itself is worn or damaged.
