Kleinn Model 502 Kraken Tri-Mount Triple Train Horn with Heavy-Duty Brass Valve, Chrome Steel

The Kleinn Model 502 Kraken is a chrome-plated steel tri-mount triple train horn for trucks and SUVs with onboard air. It's universal and is the high-flow version of the tri-mount lineup, with a bigger valve and larger airline.

You get the triple trumpet assembly, a heavy-duty aluminum triangular right-angle bracket, bolts and fasteners, a VX6003 (Vortex 6) heavy-duty brass 12V solenoid and 12 ft of 1/2" OD airline. Kleinn rates it at 155.2 dB at 150 PSI.

The brass valve and 1/2" line are what set the Kraken apart from the 500 and 501. More air reaches the trumpets, and Kleinn rates it more than 3 dB louder. The bracket mounts to a chassis frame or a rooftop, and the trumpets are reversible.

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

If you don't need the extra flow, the 501 Warlock uses the same steel trumpets with a Vortex 4 valve and 1/4" line. 1-year limited warranty.
