Kleinn Model 500 Sentinel Tri-Mount Triple Train Horn, Chrome ABS

The Kleinn Model 500 Sentinel is a chrome-plated ABS tri-mount triple train horn for trucks and SUVs with onboard air. It's universal, and Kleinn lists it as the official replacement horn for the HK6 kit.

The package includes the triple trumpet assembly, a triangular aluminum right-angle mounting bracket, bolts and fasteners, one Vortex 4 (P/N 307) 12V solenoid and 12 ft of 1/4" OD airline (Kleinn P/N 25014-1). Kleinn rates it at 151.8 dB at 150 PSI.

Chrome-plated ABS keeps the weight down while still giving you the chrome look. The right-angle bracket lets you mount it on a rooftop or under the body, and the trumpets can be flipped to point the way you need.

Horn assembly only. You'll need an air system that delivers 140-160 PSI with a tank of at least 2.5 gallons, plus a horn button. Kleinn recommends its 6350 or 6450 onboard air systems. No model-specific install guide is published.

For the same tri-mount shape in chrome-plated steel, look at the Model 501 Warlock, or the 502 Kraken with a brass valve and 1/2" line. 1-year limited warranty.
