Kleinn Model 501 Warlock Tri-Mount Triple Train Horn, Chrome Steel

Kleinn's Model 501 Warlock is a chrome-plated steel tri-mount triple train horn for trucks and SUVs running onboard air. It's universal and uses the same tri-mount shape as the Sentinel, but with steel trumpets.

In the box you'll find the triple trumpet assembly, an aluminum triangular right-angle mounting base, bolts and fasteners, a Vortex 4 (P/N 307) 12V solenoid and 12 ft of 1/4" OD airline. Kleinn rates it at 151.8 dB at 150 PSI.

It's the pick when you want the tri-mount layout with steel trumpets instead of plated plastic. The bracket mounts on a roof or under the body, and the trumpets are reversible.

This is the horn assembly only. Plan on an air system that makes 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. There's no model-specific install guide.

The 500 Sentinel is the lighter chrome ABS version. The 502 Kraken adds a heavy-duty brass valve and 1/2" airline for more output. 1-year limited warranty.
