The Giant produces a powerful high tone truck horn sound. All metal construction chrome plated throughout so to withstand the extremes in all weather conditions and to provide years of dependable service. Provided with the horn is a metal front pedestal support that is chrome plated. The support will help to eliminate trumpet vibration at high speeds and on the roughest roads. A front deflector cover provides protection against rain, road dirt, snow, and bugs from entering into the horn’s trumpet, protecting the sound and your investment. The air feeder hose connection is made through the base of the horn and is not externally visible. Installation of the high-pressure airlines is made easy with Wolo’s new flexible inlet hose with brass fittings. The Giant’s beautiful chrome appearance will look great on any truck big or small, providing an alerting sound THAT WILL BE HEARD! The kit includes, stainless steel mounting hardware, flexible inlet hose, and rubber gaskets for a watertight installation. Instruction in English / Spanish.
