Kleinn Model 220 Mini Beast Dual Train Horn with Dual 12V Solenoids, Black ABS

The Kleinn Model 220 Mini Beast is a black ABS dual train horn set for smaller trucks, SUVs and Jeeps running onboard air. It's universal, and the two horns mount independently, so you can put them in tight corners or on opposite sides of the bumper.

You get two black high-impact ABS wide-bell trumpets on black zinc alloy bases, one small and one large, each with its own Vortex 4 (P/N 307) 12V solenoid. Each horn runs its own 1/4" OD airline. Kleinn rates them at 151.8 dB at 150 PSI.

This is the horn set Kleinn uses in the HK5 kit and its vehicle kits ending in -220, so it's a direct replacement if one of those gets damaged. It's also a good choice for a custom build where there isn't room for a three-trumpet rack.

Horns and solenoids only. You'll need an air system that delivers 140-160 PSI with at least a 1.5-gallon tank, two 1/4" OD airline runs, a horn button and your own mounting hardware. Kleinn recommends its 6350 or 6450 onboard air systems. No model-specific install guide is published.

For three trumpets on a flat rack, step up to the Model 230 Beast. 1-year limited warranty.
